Ecological succession takes place because through the process of living, growing and reproducing the organisms interact with and affect the environment within an area, gradually changing it.


For example a bare patch of ground will not stay bare. It will rapidly be colonised by a variety of plants. In the process of succession , the species present in an area will gradually change.
Each species is adapted to thrive and compete best against other species under a very specific set of environmental condition . 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.

Succession is directional.

Succession will not go any further than the climax community.
