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: -Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.

Detailed explanation-3: -The process of ecological changes that establishes a series of natural communities that are replaced over time is known as succession and is of two types primary and secondary. The primary succession of water bodies such as lakes and ponds results in the conversion of these water bodies into the land community.

Detailed explanation-4: -During succession, an ecosystem starts as nearly uninhabitable and is transformed by the progressively more complex organisms that move back into the area. Pioneer species that can withstand difficult conditions move in first and begin transforming the area and making the soil better for other plant species.

Detailed explanation-5: -For example, when a tree falls in a mature forest, sunlight may again be able to reach the forest floor, which would allow new growth to begin. In this case, succession would begin with new smaller plants. Communities are always changing and growing.
