Biology

Chemosynthesis is a biological process that uses inorganic compounds (rather than sunlight as in photosynthesis) as the energy source to convert carbon compounds and nutrients into organic matter. This process is most often found at hydrothermal vents in the deep ocean, but it has also been found deep in caves all over the world.
