An organism that produces its own food from light or chemical energy and/or inorganic matter. Also called a Producer (or Primary Producer). Among terragen life forms, most green plants, many protists, and many prokaryotes are autotrophs. There are also alife and informational autotrophs/producers. Every food chain rests on autotrophs. Autotrophs in turn provide food for heterotrophs.
