Definitions for "autotroph"
an organism which is autotrophic, i. e., an organism (such as most plants and certain microorganisms) which are capable of synthesizing its own food from simple organic substances, requiring only minerals as nutrients for growth, and using carbonate or carbon dioxide as a source of carbon and simple inorganic nitrogen as a nitrogen source; the energy required is derived from photosynthesis or chemosynthesis. Opposed to heterotroph. See also auxotroph.
An organism that synthesizes organic molecules from inorganic starting materials through photosynthesis, or chemosynthesis. Autotrophs are ecologically important as they ultimately provide energy for all heterotrophic organisms.
An organism that can produce the organic molecules and energy necessary for life through the processes of photosynthesis or chemosynthesis. Autotrophs do not rely on other organisms for food. In a food web, autotrophs are producers.
