What is the usual sequence for ecological succession?

Ecological succession breaks down into three fundamental phases: primary and secondary succession, and a climax state. The study of ecological succession generally focuses on the plants present on a particular site. But animal populations also shift over time in response to the changing habitat.

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment.

Which entity will be first to colonize a bare rock?

Primary Succession

The first species to colonize a disturbed area such as this are called pioneer species (see Figure below). They change the environment and pave the way for other species to come into the area. Pioneer species are likely to include bacteria and lichens that can live on bare rock.
