Thick Growth of Young Trees. Ecological succession is the process by which natural communities replace (or "succeed") one another over time. While primary succession describes the development of an ecosystem in a barren habitat, secondary succession is the recovery of an ecosystem after most of its species have been eliminated. The Climax Stage of Ecological Succession is where the land is barren because as the result of a natural disaster. The steps of ecological succession a watercolor diagram.

Over hundreds of years these pioneer species convert the rock into soil that can support simple plants such as grasses. What these examples have in common is that the climax community is not the first one present on the landscape after succession begins: First, intermediate communities occupy the space, sometimes for many years, creating ideal conditions for the communities that follow. It gets to the point that the environment is altered so much it is no longer able/suitable to support the pioneer species; as other more adapted species outcompete it for resources. Helmenstine, Anne Marie, Ph.D. "Primary Succession Definition and Examples." Which disturbance would result in primary succession? A. harvesting What is the difference between evolution and succession? Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Succession is the response of a community to a disturbance that opens a relatively large area for invasion, or reoccupation by organisms. what kind of fragment is "near the computer"? As native species go extinct or become rare, new species enter ecosystems, and climate baselines shift, the communities that once dominated an ecosystem may be less likely to eventually return after a disturbance.
