Niche and habitat….What are they?
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
A rabbit’s habitat or address would be my garden.
Its niche would be eating the vegetables, and putting nitrogen back into the soil.
