Question

MacArthur is related with:

• A. Competitive exclusion
• B. Resource partitioning
• C. Competitive release
• D. None of the above

Answer 1

The correct option is B Resource partitioning

According to the mechanism of resource partitioning (supported by MacArthur), if two species compete for the same resource, they could avoid competition by choosing, for instance, different times for feeding or different foraging patterns. 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.
