Term Biotic
Definition

Living. Relating to any aspect of life, especially characteristics of entire populations or ecosystems. The biotic component of an ecosystem includes producers, consumers and decomposers, which are defined by the relationship that organisms have with the system’s energy and matter. Producers are autotrophic organisms which convert inorganic matter into organic matter by using sources of energy, such as the sun, to produce their own food. In turn, consumers and decomposers are heterotrophic organisms that feed on other life forms. Consumers use organic matter produced by producers and other consumers, while decomposers transform both organic and inorganic matter.

Tertiary consumers (top-level carnivores)
Omnivorous consumers (herbivores and  carnivores)
Detritivores (feed on detritus)
Chemotrophs: build organic compounds by oxidation of simple inorganic substances.

Decomposers

Saprophytes (recycle organic matter)
