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.
Secondary succession is the series of changes that occur after a disturbance (like a forest fire or hurricane) in an ecosystem. Do not confuse this with primary succession, whâ¦ich is a gradual growth of an ecosystem over a long period of time after a disturbance, such as a volcano that erupted.
