Question

Niche overlap indicates:

• A. commensalism between two species
• B. sharing of one or more resources between the two species
• C. mutualism between two species
• D. active cooperation between two species

Answer 1

The correct option is B sharing of one or more resources between the two species

Niche indicates the habitat of a particular species and the interaction of that species with the resources present in the habitat.
An organism's fundamental niche is the full range a species can occupy without interference from other species. However, inter-specific competition often forces species to occupy a much narrower niche, to which they are mostly highly adapted.
Niche overlap means that two or more species sharing the resources present in a particular niche.
