Question

What is the niche of an organism?

Options

• The physical location where an organism resides

• All organisms that compete for the same food

• The climate zone where an organism is found

• The functional role or way of life of an organism in its community

Answer 1

An organism's niche describes its 'profession' or functional role - what it does, what it eats, where it nests, and how it interacts with other species. Unlike habitat (the 'address'), the niche is about the organism's lifestyle and ecological function within the community.
