The EcoSphere's biological cycle represents a simple version of Earth's' own ecosystem. Light together with carbon dioxide in the water enable the algae to produce oxygen by photosynthesis. The shrimp breathe the oxygen in the water while nibbling on the algae and bacteria. The bacteria break down the animal waste into nutrients, which the algae utilize. The shrimp and bacteria also give off carbon dioxide, which the algae again use to produce oxygen. And so the cycle renews itself.
