Detailed explanation-2: -By Max Witynski. Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”-like a mature forest-is reached, or until a disturbance, like a fire, occurs.
Detailed explanation-3: -Which phrase best defines ecosystem? An ecosystem is a community and its surrounding nonliving environment.
Detailed explanation-4: -Species diversity is much greater in the ecosystem undergoing primary succession because the lack of soil provides a greater area for organisms to claim niches. Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species.
