The correct option is A Orderly and sequential
Ecological succession is the gradual and fairly predictable change in the species composition of a given area. There are six basic processes that occur during succession leading to the formation of a stable climax community - that is nudation, migration, ecesis, competition, reaction and stabilization. Nudation, the process of creating a bare patch of soil, is what begins succession. Then plants colonize this bare land and they either come from propagules (seeds, root fragments, plant parts or even whole plants ) that were buried in the soil or propagules migrating from somewhere else and reaching this bare land. Ecesis follows which is the successful establishment of the plant species. As the number of individuals of a species increases due to multiplication and all of these aggregate in a limited space, competition for resources ensue. This competition that occurs among the established plants leads to elimination of some species while favouring others either during establishment or later stages of succession. Reaction, is the change of environment as a result of plants dying and this continually changes the availability of resources. The end of this process is stabilization or climax. Therefore ecological succession is always orderly and sequential.
