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: -The 5 stages of Ecological Succession in successive order are-Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization.
Detailed explanation-3: -Secondary succession occurs when the primary ecosystem gets destroyed. For eg., a climax community gets destroyed by fire. It gets recolonized after the destruction. This is known as secondary ecological succession.
Detailed explanation-4: -D Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species. As ecosystems move through the stages of succession, the populations of organisms in them change.
