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: -The chemical equation for chemosynthesis is 18H2S + 6CO2 + 3O2 → C6H12O6 (carbohydrate) + 12H2O + 18S.
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: -Chemosynthesis is the process by which microbes create sugars (food) using energy released from chemical reactions. This process is used to fuel the base of the food web at hydrothermal vents and cold seep sites.
