autotrophs An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces organic compounds from carbon dioxide as a carbon source, using either light or reactions of inorganic chemical compounds, as a source of energy. An autotroph is known as a producer in a food chain. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs). Bacteria that utilize the oxidation of inorganic compounds such as hydrogen sulfide, ammonium or ferrous iron as an energy source are chemoautotrophs. Aloha.

Most broadly, all organisms fit into one of three camps: producers, consumers, and decomposers. Producers. Producers are able to produce carbohydrates from the energy of the sun through photosynthesis or, in some instances, from inorganic molecules through chemosynthesis.ecause they can produce their own food, producers are also called autotrophs. Producers form the foundation of every food chain because only they can transform inorganic energy into energy that all other organisms can use. On land, plants and photosynthetic bacteria are the main producers.
