autotroph

an organism that can manufacture its own organic requirements from inorganic materials independent of other sources of organic substrates. Autotrophs are either phototrophic (see PHOTOAUTOTROPH or CHEMOAUTOTROPHIC, energy being derived either by photosynthesis where chlorophyll is present, or from inorganic oxidation where it is absent (e.g. hydrogen sulphide is oxidized by sulphur bacteria). Autotrophs are primary producers (see PRIMARY PRODUCTION). Compare HETEROTROPH.
