Chemosynthesis is an unusual type of nutrition of bacteria, based on the assimilation of carbon dioxide СО2 due to the oxidation of inorganic compounds. In most cases, primary food production occurs in a process called photosynthesis, which is powered by sunlight. Here, the energy used to manufacture food materials is derived from a variety of inorganic chemicals (and thus different chemical reactions). Chemosynthesis is a process certain organisms use to obtain energy for the production of food, akin to photosynthesis, but without the use of sunlight. Chemosynthesis is a process of use of energy produced by inorganic chemical reactions to produce food. Chemosynthesis . Examples of biosynthesis include photosynthesis, chemosynthesis, amino acid synthesis, nucleic acid synthesis, and ATP synthesis. The energy comes from the oxidization of inorganic chemicals that the organisms find in their environment. Ecosystems depend upon the ability of some organisms to convert inorganic compounds into food that other organisms can then exploit. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulfide) or methane as an energy source. In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source.
