Question

Justify the following statement with suitable proof/examples:

‘Competing species may evolve mechanisms for co-existence.’

Answer 1

One such mechanism is ‘resource partitioning.’ 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 coexist due to behavioural differences in their foraging activities.
