Chemosynthesis requires specific inorganic compounds, such as hydrogen sulfide or methane, which serve as electron donors. Additionally, it needs a source of energy, typically derived from chemical reactions involving these compounds, rather than sunlight. Microorganisms, particularly certain bacteria, perform chemosynthesis in environments like deep-sea hydrothermal vents, where light is unavailable. Lastly, the presence of carbon dioxide is necessary, as it is the carbon source for producing organic compounds.
