Definition noun, plural: autotrophs A organism capable of making nutritive organic molecules from inorganic sources via photosynthesis (involving light energy) or chemosynthesis (involving chemical energy)
An autotroph is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions. Autotrophs are the producers in a food chain.Plants and other organisms which carry out photosynthesis are photoautotrophs (or phototrophs). Bacteria which derive energy from oxidizing inorganic compounds (such as hydrogen sulfide, ammonium and ferrous iron) are chemoautotrophs, and include the lithotrophs.hey take energy from the environment (in the form of sunlight or inorganic chemicals) and use it to create carbon-based organic molecules. Other organisms, called heterotrophs, take in autotrophs as food to carry out such functions.
