Ecological succession, a fundamental concept in ecology, refers to more-or-less predictable and orderly changes in the composition or structure of an ecological community. Apart from the regular fluctuations in species abundance related to seasonal changes, a community may develop progressively with time through a recognizable successional sequence. The changes are directional and take place as a function of time. 30 seconds. It is a predictable and inevitable process of nature as all the biotic components have to keep up with the changes in the environment.
