Detailed explanation-1: -Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat.

Detailed explanation-2: -As an ecosystem changes, older inhabitants gradually die out and new organisms move in, causing further changes in the community. This series of predictable changes that occurs in a community over time is called ecological succession. Ecological succession is slow and gradual; it occurs over a period of many years.

Detailed explanation-3: -Ecological succession is the gradual and fairly predictable change in the species composition of a given area. During succession, some species colonies area and their population become more numerous, whereas, the population of other species declines and even disappears.
