An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms....

of nutrition (trophic levels), the other being autotrophs (auto = self, troph = nutrition). Autotrophs use energy from sunlight (photoautotrophs) or oxidation...

Photoautotrophs are organisms that can utilize light energy from sunlight and elements (such as carbon) from inorganic compounds to produce organic materials...

A chemotroph Greek words “chemo” (meaning chemical) and “troph” (meaning nourishment) is an organism that obtains energy by the oxidation of electron donors...

anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs). The electron or hydrogen donors are taken up from the environment. Organotrophic...

chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending...

responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these...
