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 important for the growth and development of an ecosystem. It initiates the colonization of new areas and the recolonization of the areas that had been destroyed due to certain biotic and climatic factors.

Detailed explanation-3: -Which of the following is true of ecological succession? Pioneer organisms move into new communities first.

Detailed explanation-4: -Ecological succession occurs due to the changes in the physical environment and population of species. It may also occur when the conditions of an environment suddenly and drastically change. For example, forest fires, wind storms, and human activities all greatly alter the conditions of an environment.
