D

Explanation: 

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.

Detailed explanation-2: -Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as soil is already present, and seeds, roots, and the underground vegetative organs of plants may still survive in the soil.

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: -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.
