What is an animal's niche? How many dimensions can a niche have? Can animals share a niche? - Answer-•the functional role/job of an organism considered in the environment it lives in •many dimensions, but can be divided to 3: the ecological 'space' it fills, and the physical space it literally fills and time when they do •no animals can share the same niche! What is a specialist vs a generalist? - Answer-•specialist: narrow niche, limited diet, restricted to a particular location...
