D
Natural Selection
Explanation: 

Detailed explanation-1: -This series of changes is called ecological succession.

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.

Detailed explanation-3: -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-4: -The 5 stages of Ecological Succession in successive order are-Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization.

Detailed explanation-5: -If we consider an area where life starts from scratch through the process of succession, it is known as primary succession. However, if life starts at a place after the area has lost all the life forms existing there, the process is called secondary succession.
