niche

the sum of the characters that determine the position of an organism in its ECOSYSTEM. This includes all the chemical, physical, spatial and temporal factors required for the survival of that species and which limit its distribution and growth. A niche is characteristic of a SPECIES, and no two species occupy the same niche in the same environment in each others’ presence. However, a different species may occupy the same niche in the absence of the normal occupant from that habitat.
