Question

Several species of warblers can live in the same spruce tree ONLY because they.

Answer 1

The correct answer is C.

Several similar species can live in the same habitat only if they occupy different ecological niches. An ecological niche presents not only the physical space in the habitat that the species occupies, but also the place in the food web and the role of the species in the ecosystem. Therefore, in the example of warblers, the species can live in the same spruce because they use different resources and strategies of survival.

Answer 2

Several species of warblers can live in the same spruce tree only because they occupy different nitches within the tree. So option "c" is the correct option as far as the given question is concerned. These birds may not be of the same species but they do have some similarities like they are very vocal and can be rarely seen but definitely heard. All species of warblers are insectivorous and also very small. As they are small so identifying them can be very difficult for a person. These birds are mostly dull greenish or brownish in color.
