Many years ago, NASA scientists were studying ways to build spaceships that could keep astronauts alive for long space journeys. They wanted the environment inside the spaceship to maintain itself, producing food and oxygen for the crew and keeping the air and water clean and reusable. As part of NASA’s experiments, they discovered how to make a self-contained living world inside a closed glass container. Because these tiny, living worlds were so beautiful and helped people understand about the balance of nature, NASA gave the technology away so that these little worlds could be made and sold in great numbers. The tiny worlds are called Ecospheres.
What is Ecosphere, how does it work?
The Ecosphere(R) is a tiny working model of the Earth. It contains the same essential elements that are found on our planet- air, water, life (algae, microorganisms and shrimp) and land (gravel and gorgonian). Life functions in the Ecosphere just as it does on Earth.
Light： sun or artificial light makes the algae grow. Oxygen： Algae produce oxygen for the shrimp. Food： Shrimp eat the algae and the bacteria feed on the waste from the shrimps’ digestion Waste： Shrimp produce waste—carbon dioxide from “breathing” and solid waste from eating. Nutrient： Bateria break shrimps' digestion down into nutrients. The algae use the nutrients, carbon dioxide and light energy to grow back, so the shrimp will have yet another meal.
