what is the process of succession
Succession is the process by which new community gets established at an area which had been uninhabited. The community which gets established at the site is called climax community. It is the aggregation of changes of species structure in an ecological community over time.
Ecological succession is the observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval, or they may even vanish from the ecosystem altogether.
