Question

Answer 1

Answer: E. climax

An ecological succession refers to the changes that occur in a biotic community with respect to the changes occurring in the abiotic or non-living factors such as soil, weather, temperature, sunlight and others. These changes occur with respect to the time until the ecosystem attains the stability.

A climax community is the end stage of the ecological succession. In this community the living species attains equilibrium which means no further change will occur in these organisms. These species are fit for the survival in the changing environment. Hence, these species are stable.      

Answer 2

E.climax, because the climax community is composed of species best adapted to average conditions in that area.
