Definition:
The phenomenon of orderly transition from one biotic community to another
and is also known as ecological or natural succession. Natural succession
occurs because the physical environment may be gradually modified by the
growth of the biotic community itself, such that the area becomes more
favorable to another group of species and less favorable to the present
occupants.
