Detailed explanation-1: -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. Ecological succession is a fundamental concept in ecology.
Detailed explanation-2: -Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.
Detailed explanation-3: -The number and types of animals remain constant. The gradual and predictable change in species composition occurs in a given area. The changes lead to a community that is in near equilibrium with the environment and is called pioneer community.
Detailed explanation-4: -What changes occur during ecological succession? Assertion: During an ecological succession, the number of species increases, the community biomass increases and the community’s ratio of respiration to photosynthesis also increases.
