Which best describes a birds role as it eats seeds ?

The answer is niche. Niche is the role and position of species in the environment. Thus, bird’s role as it eats seeds is the example of niche. Habitat is an area inhabited by a particular species, so bird's role cannot be habitat. Parasite is an organism that lives on/in another organism (host) at the expense of the cost. Also, predator eats its pray. If a bird eats seeds, it is not parasite or predator.

Is this a question? i'm confused
