Question

five different warbler species can coexist on the same spruce tree because each species ________.

○ eats the same food. (in other words, theyre all eating the same things, in the same locations.)
○ mutually benefits the other species.
○ is a parasite on the other species.
○ occupies its own ecological niche.

Explanation:

To determine why five warbler species can coexist on the same spruce tree, we analyze each option:

• The first option is incorrect because if species eat the same food in the same locations, competition would likely prevent coexistence.
• The second option is incorrect as mutual benefit (mutualism) is not the primary reason for multiple species coexisting in the same habitat in this context.
• The third option is incorrect because being a parasite on other species would not lead to stable coexistence of five species.
• The fourth option is correct. An ecological niche refers to the role a species plays in its environment, including its habitat, food sources, and interactions. By occupying their own unique ecological niches, the warbler species can reduce competition and coexist, as they have different resource requirements or use resources in different ways (e.g., different feeding positions on the tree, different prey, etc.).

Answer:

D. occupies its own ecological niche.
