Summary
A habitat is where an organism lives; a niche is its role and resource use within the ecosystem.
In depth
The fundamental niche is the full range of conditions a species could use; the realised niche is the part it occupies after competition and predation. G. E. Hutchinson described niche as an n-dimensional hypervolume.
No two species occupy the same niche indefinitely.
Resource partitioning allows similar species to coexist. Niche breadth indicates generalists and specialists. Specialists are more vulnerable to environmental change.
Common mistake: a niche is not a place; it is a role plus the conditions needed.
