Endogeny (biology)

Endogenous substances and processes are those that originate from within a system such as an organism, tissue, or cell.[1]

For endogeny or endogeneity in other contexts, see Endogeneity and Exogeny.

Exogenous substances and processes, which originate from outside of the organism, such as drugs, contrast with endogenous ones.

Many animals are endogenous but mostly ants, many ant species go into hibernation no matter the temperature, moisture, weather, light, etc.
