39. Closed Ecological Systems "Eco?


SEC closed ecological system


independent A nice little world? "Does not that sound a children's story?? The challenge is exciting!

In Chapter 5 ( Play ecosystems ) comment a bit on these ecosystems related to the vision of Perpetuum movile had Leonardo da Vinci : an independent self-propelled machine forever. A closed ecosystem is a real challenge of biological and chemical equilibria, accompanied by some type of energy source that's active. All this balance must be sustained in isolation, allowing life contained therein prosper in a sustainable and healthy.

Two proposals closed worlds

In Wikipedia, the free encyclopedia Internet defines what a Closed Ecological System :

Closed ecological systems (SEC) are ecosystems that do not exchange matter by any party outside the system. Although the land itself can be clearly seen in this definition, the term is used most often to describe much smaller artificial ecosystems. Such regimes are relevant and can potentially serve as a life support system during space flight , in space stations or submarines.
.

not really a completely closed system, because energy (especially light and heat) can enter and leave the system.

The large ecosphere can sustain life for several decades

In a closed ecological system, any waste produced by a species should be used for at least another species. If the purpose is to maintain a way of life higher, for example a mouse or a human, such as waste carbon dioxide the feces and urine should eventually become the oxygen, food and water.

Maybe now they are discovering a new concept of independent eco-assisted technology: PASCO zooténia ©

A closed ecological system must contain at least one autotrophic organism (producing their own food like plants and some bacteria). While agencies chemotrophs (which gets its energy by metabolizing waste from other agencies) and photoautotrophs (that gets energy from light) are plausible, almost all closed ecological systems to date are based on a photoautotrophs as green algae.

"artificially create a closed ecosystem?

This is a topic that fascinates many people. Is it possible to artificially create a closed ecosystem and sustainable self-sufficient?

The aesthetic appearance of the proposed closed ecosystem is unattractive, but inside it has generated a micro

There are many answers to this question Internet, and increasing ecological and biological literature. Specialized forums there are people who claim to have achieved an aquarium or terrarium that has remained alone. But always for a specified period of time, variable in each experience. The previous paragraph explains that " is not really a completely closed system, because energy (especially light and heat) can enter and leave the system ."

Finally, a closed ecological system when it has finished its biochemical imbalance

The smaller (microscopic dimensions) is a space dedicated to develop an ecosystem, this is easier. The necessities of life are more adaptable to a microscopic level because it requires less energy consumption. There are real microworlds that we can not know if it is not through a microscope.

in a drop of water can be a microcosm of microscopic life, represented by bacteria and microbes

also know that we can "hold" open green spaces large. The larger is the extension of an area to support life, it also increases the capacity of adaptability of the species that occupy it. And also increases the ease of obtaining energy (access to renewable and sustainable sources such as sunlight, wind, water, etc.).

The interior of a conditioned space for the development of nature. Ecosystems are looking to develop alone. Here we address this issue with Biosfera2 and Eden.

writer and scientist Isaac Asimov , said:

If we make a metaphor between a ecositema and chair, both are kept in perfect balance, the chair for being fixed with its four legs on the ground for their own weight. But when we analyze a closed ecosystem, is like analyzing a chair that has gotten the full balance on one leg raised.

If you want to create something close to a closed ecosystem and independent, in the simile of the chair, we must hold to be lifted on one leg, otherwise always be rocked to one side, and possibly for a few seconds can be maintained in the air ... but always end up unbalanced. Indeed

can create a closed ecosystem, but we have to assist you before or after to restore balance.

DEFINITION OF CLOSED ECOSYSTEM

As we want to give a rigorous and objective, we try to learn from the best information sources contrasted serious. Transcribe very understandable definition of closed ecosystems, published in the journal Artificial Intelligence Chilean. In this case we have wanted to illustrate visually graphic designs to make it easier to explain.

We will prepare the recipe for a closed ecosystem


1. A closed ecosystem is a man-made ecosystem where there can be no material exchange with the outside.

Well, we have introduced the field ....

2. Living things a closed ecosystem can be divided into 3 groups: producers, consumers and decomposers.

prepare a container specially designed to be hermetically sealed

3. All closed ecosystem must contain at least one species of autotrophic organism.

4. Most closed ecosystem used phototropic organisms such as green algae.

In our case, we will help with biotechnology (animal husbandry). These devices are vital to balance internal parameters, recycling waste into oxygen, water and food


5. If the purpose of closed ecosystem is to maintain higher life forms such as a mouse or a human being, it is necessary that feces, urine and carbon dioxide are converted into food, water and oxygen.

... And here the creature autotrophic, vital part of the closed ecosystem

6. The microecosystems are ecosystems that measure only microns, typical of bacteria and other microscopic life. As can be seen only under a microscope, are not interesting for leisure nor decorative, but they can help us better understand how to build mini-ecosystem closed.

EXAMPLES OF CLOSED ECOSYSTEMS

Several proposals called Closed Ecosystems:

Bottle: introduce a transparent plastic bottle of 1.5 liters, a bit of mud at the bottom of a stream, water, water fleas (Daphnia pulex ) and algae ( Riccia .)

Closing the bottle and letting the sun, water fleas last more than 3 years. The larger the bottle, but last year the water fleas.

The Daphnia, interesting animal because it helps to purify water, but small for the human eye

ecosphere: is a crystal ball that contains shrimp, filtered seawater, algae, bacteria, gorgonian and gravel.

The origin of the Ecosphere goes back several decades ago when they were developed by Joe Hanson and Claire Scientific Folsom.



The ecosphere stores light energy and converting it biochemically. The light, along with carbon dioxide water allows algae to produce oxygen.

The shrimp breathe the oxygen in the water and feed on algae and bacteria. The bacteria convert animal waste into nutrients for algae. Algae and bacteria also produce carbon dioxide using algae to produce oxygen.


Temperature also affects health of the ecosphere. Maintain a constant temperature increase viability.

say that in an area of \u200b\u200b21 cm shrimp actively survive and reproduce for over 6 years. Aquarium

closed: is an unnatural ecosystem in which it is to maintain aquatic species as long as possible and they can interact in balance. Many people try their aquariums may require minimum maintenance. Some have managed to maintain an aquarium closed for years, without filtering the water with machines or to provide any nutrients.

An aquarium that offers the greatest independence of ecosystem, creating

There aquariums of various types: cold, fresh water, heat and salt water. Living beings are using algae, bacteria, mosquito larvae, shrimps, crabs, invertebrates and even fish.

The Aquaponics is another solution to maintain self-sustaining ecosystem in balance virtually closed. From here, we recommend visiting research osmaroi , of \u200b\u200bwhich we do not lose your progress. Is published in the WEB The Rinconete © osmaroi

Terrarium closed: is a type of crop that requires no care. The only task performed is the process of introduction of the specimens inside the terrarium. In closed terrariums are often grown humidity loving plants with little need for lighting solar. A closed terrarium is not good for the copies gross, flowering plants or fast growing.


ecosphere
But the definition is not always understood as a space, either spherical or otherwise made possible by man-made. Ecosphere is also understood as our planet, carrying within it the bulk of global biodiversity (Life).


transcribe, for their informative value, an excerpt from the book written by ECOLOGY Rafael Chaves Julian Monk and published by University Publishing details of Costa Rica (excerpt): Ecosphere

Spaceship Earth

p. 113. 4.

The ecosphere is the entire set of abiotic and biotic elements of the world. In other words, the ecosphere is the region consisting of the outer layer of the Earth, oceans and biomes it contains. To understand, imagine that we are astronauts. (...)

other hand state:

(...) The Earth is like a big spaceship, without which we would die. Ecologists similar study of it in bottles and submarines, where so everything is recycled, but without the stability of a natural ecosystem.


CLOSED ECOSYSTEM TECHNOLOGY

Published
World Title: Ecosystem pocket
As happened to Carl Sagan in 1986, I have a world that has arrived in a cardboard box labeled 'very fragile'. It is a crystal egg, hermetically sealed, home to algae, bacteria and four shrimp. A scientifically perfect world where light life has come. It is an ecosphere, a complete ecosystem, treated with care, I can watch them grow over the next four or five years.

The ecosphere is the product of research developed by NASA's Aerospace Laboratory, seeking ways to carry, in the future, ecosystem distant planets like Mars. The ultimate aim of the space agency is to install a closed system that can meet the needs of water, air and food for astronauts to land on a planet, so they can live in a kind of 'ecosphere' oversized. For NASA, the ecosphere planet Earth is like a small-scale and shrimp, the human species. (...)


So the result of years of research by NASA gave birth to the ecosphere, small ecosystems in balance encased in glass with a little water. They live red shrimp, algae and microorganisms active in a deciliter of filtered seawater. Following all citizens can live between two and five years, although there have been cases of some areas that are in perfect working ten and 18 years after his 'birth'.

WHAT IS A Ecosphere?

Carl Sagan wrote a very instructive little story enclosed ecosystems in a fun titled: World arrived in the mail I

Carl Sagan (chapter 37. Exo Ecosystems: Life in the Universe ), popular scientist of NASA, wrote in 1986 in the magazine Parade Magazine by Carl Sagan, a really interesting letter of which transcribe what is most important. For those interested in reading it in full (highly recommended), you can access it via the site estamosen.es offering the authorized translation into Castilian of World arrived in the mail I and also other very educational, A Garden on Mars: Complete translation

: estamosen.es .
Title: World arrived in the mail I
Author: Carl Sagan.
. Dr.
Carl Sagan, director of the Laboratory for Planetary Studies Cornell University (Laboratory for Planetary Studies at Cornell University), awarded the Medal of Environment Programme United Nations (UN) in New York and as with the Honda Award : "Contributions to ... a new era of human civilization."

A part of having a prodigious mind, Carl Sagan had a great sense of empathy

The world I came in the mail. came in a box labeled "fragile" and stating that it contained a drawing that could be broken glass. I opened it carefully, afraid to discover remnants of broken glass. But it was intact. With both hands, pulled him out of the box and put it to light. It was a transparent sphere, water filled more than half. marked with the number 4210. World number 4210: there must be many similar worlds. Carefully, put it as instructed and I began to contemplate.

I could see the life within it: a set of branches, some with filamentous algae, and six or eight small animals, almost all pink, (at least that is what appeared ) between branches.

addition, there were hundreds of other creatures, like fish in the waters of the oceans on Earth, but they were all microbes, too small to be seen with the naked eye. Clearly animals pink shrimp were some kind of variety they made appropriate to stay in those conditions, that caught my attention immediately because they were very active. Some walked around the bush with ten legs, moving other appendages at the same time. Another was to give all their attention on some branches, to eat a green filament.


(...) Some were pale (almost transparent), while others showed a reddish orange color.

In a way, of course, they were different from us: they had their skeletons on the outside of their bodies, they could breathe in the water, and a kind of year was placed near their mouths. They seemed concerned about their appearance and cleanliness, using a pair of pliers that have as a brush. Occasionally could be seen wiping one of them himself.

But otherwise it was beings like us, with their brains, hearts, blood and eyes. That is something that could not be ignored. That apparently disordered set of appendages for swimming propelled by throwing water contrasted with the precise purpose of their movements. When they arrived at their destination handled the filaments of algae with the precision, sensitivity and know-how of a "gourmet." Two of them, more adventurous than the rest, prowled the world ocean, swimming over seaweed, surveying his domain.

After a while you begin to distinguish individuals. A shrimp will move, shedding its old skeleton and making room for new. After that, you'll see something transparent, hanging from a branch of a rigid way, while still occupying his old life with his new shell.
also hosts one who is missing a leg, has there been a battle raging between the shrimp? Perhaps due to a sentimental struggle?
From certain angles, the surface of the water is like a mirror, and a shrimp can see their own reflections. Will you be able to recognize yourself?

From other angles, the curvature of the glass makes them look bigger, so I can see in detail how they really are. I realize that they have whiskers. Two of them swim to the edge of the water and spin again. Then, return to the depths, arms crossed casually, as if to indicate they have not found anything new with your experiment. It seemed nice.


If I can clearly see a shrimp due to the curvature of the glass, it also should be able to see me, or at least to my eye (something like a black disc, surrounded by a greenish-brown crown.) In fact, sometimes when I start to look any handling the algae, it seems that he realizes and looks at me. We have crossed our eyes and I wonder what he will think about what he sees.

After a day or two of preoccupation with work, I wake up, I give out my world of glass ... and all the shrimp seem to be gone. I blame myself. I should not feed them or give them vitamins, or change their water or take them to the vet. All I have to do is make sure that not expose the system to too much light or too long in darkness and always kept at temperatures from 5 to 30 º C: 40-85 degrees Fahrenheit (above those limits, I imagine preparing a cake and not an ecosystem). Do I have died due to lack of attention?.
.
But then I see an arm protruding antenna, and I realize I still enjoy good health. It's just shrimp, but after some time a concern just for them.


If you are in charge of one of these worlds, and consciously worry about the levels of temperature and light, then you end up realizing what is inside (whatever your thinking at first). But if they are sick or dying, you can not do anything to save them.

In a way, you are much more powerful than them, but they do things (like breathing under water) that you can not. You're limited, painfully limited. You wonder if it is cruel to put them there. But you make sure there are at least safe from other dangers such as whales, oil spills or cocktail sauce.


The ancient skeletons that move off the shrimp, like the carcass of a dead shrimp do not remain long. Serve as food for shrimp and other organisms invisible part of the world's oceans. That way you realize that these creatures not work in isolation, but that "we need others. Some take care of others (in a way that I would consume oxygen in the water and produces carbon dioxide.
.
Algae consume carbon dioxide, water and oxygen. They breathe the gases disposal of the other party. Its also solid waste cycling among animals, plants and microorganisms. In this little Eden, the inhabitants are closely related to each other.


The existence of shrimp is much more fragile and precarious than of other beings. Algae can live without shrimp much longer than they could do without algae shrimp. The shrimp eat algae and microorganisms, but primarily consume algae light.
.
Unlike what happens in an aquarium, this miniature world is a closed ecosystem.
.
The light enters, but nothing else (no food, no water, no nutrients). Everything must be recycled, just like on Earth. In our world (much larger) we also live in the other, breathe and eat waste the rest. Similarly, the life of our world is maintained by light. Sunlight that passes through the air, is used by plants combine carbon dioxide and water into carbohydrates and other nutrients, which are the staple food for the animal world.

Our big world is very similar to this miniature world, and we are very similar to shrimp. But there is at least one difference: Unlike the shrimp, we do we can change our environment. We can make ourselves just as a careless owner of one of these areas of glass can cause shrimp.
.
If we are not careful, can overheat our planet with greenhouse or cool and darken it by a nuclear war. With acid rain, the hole in the ozone layer, chemical pollution, radioactivity, deforestation of tropical forests and a dozen more assaults on the environment, we are taking our little world in ways difficult to understand. Our considered advanced civilization may be changing the delicate ecological balance that has been established for 4 billion years of life on Earth.

crustaceans such as shrimp, are much older than humans or primates or even mammals. The algae are about three billion years or more on Earth. They have been working together (plants, animals, microbes) for a long time. The functioning of organizations in my area is ancient, far more than any culture we know. The need to cooperate has unfortunately been lost as it has progressed in the evolutionary process.
.
Initially, those agencies not cooperating who did not work together with others, disappeared. You never can happen to a shrimp, for instance, destroy a garden of algae to build a parking garage. Cooperation is encoded in their genes. Its nature is based on cooperation.
But we humans are newcomers, emerging several million years ago.

Our current technological civilization has only several hundred years. We have not had much experience of interspecies cooperation (or intraspecies). Just look at the short term and to think hard long term. There is no guarantee that we are wise enough to understand our planetary ecological system closed, or we can modify our behavior according to that understanding. Our planet is indivisible.
.
In North America, we breathe the oxygen generated in the Brazilian rainforest. Acid rain polluting industries in the American Midwest destroys forests of Canada. The radioactivity of the Soviet nuclear accident commits the economy and culture of Lapland. The combustion of coal in China heats Argentina. The disease spread rapidly to distant points the planet and require a global medical effort to be eradicated. And, of course, nuclear war threatens all. One way or another, we humans are united with our neighbors and with other animals or plants around the world. Our lives are interconnected.
.
Yes we are not blessed with instinctive knowledge that allows us to make our technological world a safe and balanced ecosystem, then we should try to figure out how to build it. We need more scientific research and more restraint too optimistic to think that a "Great Ecosphere owner "in the sky will be responsible for correcting our environmental abuse. Our business.
.
should not be so difficult that it is impossible. Shrimp with brains the width of a thread you know. Algae know. Single-celled organisms know. It is high time that we learn to do the same.

NOTE: On this occasion, we have discussed a fascinating subject, attended by various sources.
