Question

Mac Arthurs vision of five closely related species of warbles living on same tree were able to avoid competition and co-exist by behavioural difference. This is an example for

• A. Competitive release
• B. Resource partitioning
• C. Competitive exclusion principle
• D. Adaptive radiation

Answer 1

The correct option is B Resource partitioning

Resource partitioning is the phenomenon when there are many species living in the same region but have adapted to different resources. This causes a reduction in the fight for the same resource. When there are five closely related species of the warblers on the same tree without any competition, this type of behavioral difference is due to resource partitioning.

Thus, the correct answer is option B.
