How do autotrophic organisms obtain their food?
An autotroph is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions. They are able to make their own food and can fix carbon. They do not utilize organic compounds as an energy source or a carbon source. Autotrophs can reduce carbon dioxide, add hydrogen to it to make organic compounds.
