What is the diffrence between a niche and a habitat (biology and ecology wise)?

Answer 1

A niche is a space of existence like a Tubafex "blood worm" which are found in oxygenated streams. They evolved into being in the habitat of a stream with less oxygen. Where the niche is the way the organism makes a living, living in oxygen less brooks.

A niche is the singular space or lifestyle of a specie.

A habitat is in describing the the whole area and system. Black capped woodpeckers are found in mostly wooded habitats.

Answer 2

Niche does not mean a small space, not in ecology. It means both the space and the role that a species have within an ecosystem: "The ecological niche of an organism depends not only on where it lives but also on what it does (how it transforms energy, behaves, responds to and modifies its physical and biotic environment) and how it is constrained by other organisms." - E.P. Odum, Fundamentals of Ecology, 3rd edition, p. 234. Odum, one of the most famous ecologists went on to say, "it may be said that a habitat is the organism's address, and the niche is its 'profession'..." (Source: same page).

Answer 3

A niche is kinda like the specialized job within a habitat. The habitat is the environment.
