Detailed explanation-1: -Ecological succession leads to the sustainability of life in an ecosystem. Succession is the observed process of change in the species structure of an ecosystem. The community begins with relatively few pioneering plants and animals and develops through stages of increasing complexity until it becomes stable.

Detailed explanation-2: -D Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species. As ecosystems move through the stages of succession, the populations of organisms in them change.

Detailed explanation-3: -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-4: -In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed-disrupted-then recolonized following the disturbance.

Detailed explanation-5: -Secondary succession, the more common type of succession, occurs on a surface where an ecosystem has previously existed. It occurs in ecosystems that have been disturbed or disrupted by humans, animals, or by natural processes such as storms, floods, earthquakes, and volcanoes.
