According to MacArthur's observations, five closely related species of warblers living on the same tree were able to avoid competition and co-exist primarily due to:

Options

  1. ACompetitive release following the removal of a superior competitor
  2. BBehavioural differences in their foraging activities
  3. CMorphological variations in their beak structures
  4. DProduction of poisonous substances to deter rivals

Correct answer

B. Behavioural differences in their foraging activities

Step-by-step solution

MacArthur showed that five closely related species of warblers living on the same tree were able to avoid competition and co-exist due to behavioural differences in their foraging activities. This is a classic example of resource partitioning, where species evolve to share resources by utilizing different parts of the habitat or employing different foraging strategies.

Answer: Behavioural differences in their foraging activities
