Detailed explanation-1: -Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food or energy. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium.
Detailed explanation-2: -Chemoautotrophs can use inorganic energy sources such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia or organic sources to produce energy.
Detailed explanation-3: -Chemoheterotrophs can generate ATP from organic molecules using two different mechanisms: respiration and fermentation.
Detailed explanation-4: -In these places, producers called chemoautotrophs use the energy stored in chemical compounds to make organic molecules by chemosynthesis. Chemosynthesis is the process by which carbon dioxide and water are converted to carbohydrates.
