How ecosphere works ? The EcoSphere is like a biological battery. The energy gained through light is stored and biochemically transformed. The base for the algae to produce oxygen is photosynthesis, for which the algae require light and carbon dioxide. The shrimp breath the oxygen produced by the algae and eat some of the algae and bacteria in the system. The bacteria is also useful in many ways. It transforms the waste, which is produced in the system, into reusable nutrients for the algae. To close the circle of life and interdependence in the EcoSphere, the shrimp and bacteria both create carbon dioxide which is again needed by the algae to start the circle with photosynthesis. Through this distribution of labor the EcoSphere achieves a balance of nature in its most simplistic form.
