In 1977 scientists were shocked to find an abundance of life in a a seemingly toxic, super-heated environment, deep in the ocean. How could these living things survive centered around underwater smoking chimney, gushing super-heated chemical fluids into the deep sea?
Most life on earth uses sun as its power source. Trees and plants use the energy in sunlight to combine water and carbon dioxide to make sugar, this process is called photosynthesis. In the deep ocean, many hundreds of meters away from the sun's rays, another process is taking place. Is called chemosynthesis, Tiny microbes use chemical energy instead of light to combine water and carbon dioxide to make sugar.
