Question

Niche overlap indicates

• A. Sharing of one or more resources between the two species
• B. Mutualism between two species
• C. Active cooperation between two species
• D. Two different parasites on the same host

Answer 1

The correct option is A Sharing of one or more resources between the two species

The coexistence of two similar species in the same ecosystem is possible until and unless they share the same niche. In ecological terms, a niche is related to the behaviour of a species living in a particular environmental condition. There is sharing of the resources between the two species and this results in competition, parasitism, etc.

Thus, the correct answer is option A.
