What are chemosynthetic bacteria?


wiseGEEK Writing Contest

Without the sun, most life forms on Earth would die, however chemosynthetic bacteria are unique in that they do not rely on the sun's light to make their energy. Found in some of the darkest reigions of our planet, mostly the ocean floor, these life forms use carbon dioxide and water as well as hydrogen sulfide, found in deep hydrothermal vents to release glucose and sulfuric acid. Another really remarkable thing about these organisms is that they are thought to be some of the oldest organisms on our planet and probably the organisms that would start life on other planets.
