As an ecological term, autotrophs are also called independent vegetative organisms, and the corresponding word is heterotrophs. Organisms that survive and reproduce by inorganic nutrition are the corresponding words of organic nutritious organisms.

Organisms that assimilate carbon by using energy obtained from chemical dark reactions such as respiration or photochemical reactions are called chemoautotrophs and photoautotrophs respectively.

An organism that feeds on inorganic substances and can produce organic substances for its own growth. Including all green plants and chemosynthetic bacteria, they are producers of organic matter in the ecosystem and the basis of the food chain in the ecosystem.

Extended data:

In terms of species, autotrophs can be divided into photoautotrophs and chemoautotrophs.

Photoautotrophic:

Photoautotrophic type refers to the autotrophic type that uses light energy to synthesize organic matter from carbon dioxide in the atmosphere and water in the soil.

Autotrophic type:

The chemoautotrophic type refers to the autotrophic type that uses the energy released by the oxidation of ammonia into nitrate ions to synthesize organic matter from carbon dioxide in the atmosphere and water in the soil.
