Question

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

have different habitats within the tree.

don’t eat food from the tree.

occupy different niches within the tree.

can find different temperatures within the tree.

Answer 1

The answer is occupy different niches within the tree.

Niche is the role and position of species in the environment.
Here, the environment is the spruce. And several species of warblers live in the same environment (the spruce). They must have different roles and positions on the spruce, other words, they must occupy different niches within the tree. Otherwise, competition would occur.
