This would be an example of secondary succession because the vegetation can still recover. Experts are tested by Chegg as specialists in their subject area. [21] There are "opportunistic" or "pioneer" species that produce great quantities of seed that are disseminated by the wind, and therefore can colonize big empty extensions. The researcher set up various mycorrhizal communities at disturbed beaches in different locations on the east coast of the United States.

The environment includes the species' responses to moisture, temperature, and nutrients, their biotic relationships, availability of flora and fauna to colonize the area, chance dispersal of seeds and animals, soils, climate, and disturbance such as fire and wind. It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. In extreme cases reverse succession occurs when overgrazing pushes a woodland back towards acid grassland, and even to bare, eroded peat hags. During a succession, different groups of plants grow at a site over time. Mutation is a change in the base sequence of DNA in a gene that is usually significant enough to alter the appearance or function of the organism.
