Detailed explanation-1: -Explanation: Species diversity does not contribute for ecological succession.
Detailed explanation-2: -Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
Detailed explanation-3: -For example, after a forest fire that kills all the mature trees on a particular landscape, grasses might grow, followed by shrubs and a variety of tree species, until eventually the community that existed before the fire is present again.
Detailed explanation-4: -The 5 stages of Ecological Succession in successive order are-Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization.
