Niche

in Ecology

the relational position of a species or population in its ecosystem to other species or populations. A shorthand definition of niche is how an organism makes a living:

“The ecological niche of an organism depends not only on where it lives but also on what it does. By analogy, it may be said that the habitat is the organism’s “address”, and the niche is its “profession”, biologically speaking.”

Odum – Fundamentals of Ecology – W B Saunders 1959

The ecological niche describes how an organism or population responds to the distribution of resources and competitors.
