Question

true or false no two species can fill the exact same niche within a habitat. true. overlap between niches can not be 100%. false. niches frequently have overlap.

Explanation:

According to the competitive exclusion principle, no two species can coexist in the same habitat if they occupy the exact same niche. This is because they would compete for the same limited resources, and one species would out - compete the other. While niches can overlap to some extent, a 100% overlap (exact same niche) is not sustainable.

Answer:

True. Overlap between niches can not be 100%.
