Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Homeostasis is the tendency of biological systems to maintain relatively constant conditions in the internal environment, while continuously interacting with and adjusting to changes originating within or outside the system. In ecology, climax community is a term that expresses a biological community of plants and animals and fungi which, through the process of ecological succession in the development of vegetation in an area over time, had reached a steady state. This equilibrium was thought to occur because the climax community is composed of species best adapted to average conditions in that area.
Therefore, the correct answer is option B.
