Answer AND Explanation:
In the process of succession, the species in an area will gradually change. Each species is adapted to survive and competes with other species under specific sets of environmental conditions. If these conditions change, then the existing species will be replaced by a new set of species which are better adapted to the new conditions that have evolved.
This process helps an ecological community to undergo a predictable change following the initial colonisation of a new habitat. The succession that occurs in new habitat uninfluenced by pre existing succession is called primary succession, where as succession that follows disruption of a pre existing community is called secondary succession.
