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
- ACompetitive release following the removal of a superior competitor
- BBehavioural differences in their foraging activities
- CMorphological variations in their beak structures
- 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
Answer: Behavioural differences in their foraging activities
