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.

Primary succession begins when organisms move into a landscape previously devoid of all living things following a major disaster, such as the eruption of a volcano that completely destroys the prior environment. This succession involves a total rebuilding of the ecosystem.rimary succession is the population of an ecosystem that was previously completely uninhabited, while secondary succession involves the re-population of a diminished vegetative community.
