Detailed explanation-1: -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-2: -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-3: -The 5 stages of Ecological Succession in successive order are-Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization.

Detailed explanation-4: -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.

Detailed explanation-5: -Answer: D it is a random process, The process through which the mix of species and environment in a given region changes over time is known as ecological succession.
