A habitat is the location in which an organism, population, species or community lives.
Use habitat for place and niche for how the organism survives and interacts. One habitat can contain many niches.
A rocky intertidal shore is a barnacle habitat; tolerance of exposure and competition describe its niche.
Niche; it describes behaviour and role, not location.
Habitat answers where; it does not describe ecological role.
