Detailed explanation-1: -Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.
Detailed explanation-2: -Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways.
Detailed explanation-3: -Chemosynthesis is the process in which bacteria make food with chemical energy. In this process, one or more carbon molecules are converted into organic matter.
Detailed explanation-4: -The chemical equation for chemosynthesis is as follows: 18H2S + 6CO2 + 3O2
