primary succession
secondary
The basic thing to know, is the primary succcesion occurs w/o any dirt presnt. The pioneer species, lichens and mossess, break down any rocks present to create soil. Secondary succesion occurs when there is already soil present, but the land has been cleared, like after a fire.
primary succession
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires. Secondary succession is usually much quicker than primary succession for the following reasons:There is already an existing seed bank of suitable plants in the soil.Root systems undisturbed in the soil, stumps and other plant parts from previously existing plants can rapidly regenerate.The fertility and structure of the soil has also already been substantially modified by previous organisms to make it more suitable for growth and colonization.It occurs in land and marine communities - Novanet
primary succession
Primary succession occurs after the complete wipe out of vegetation. After the wipe out occurs, small shrubs and grasses grow. Secondary succession however, occurs when there has been destruction to the land, but not enough to completely devastate the area. Hard woods grow during secondary succession.

Secondary succesion is the succession that occurs after the initial succession has been disrupted, and some plants and animals still exist. It is usually faster than primary succession.
In places no land has ever been, so like when a volcano erupts and forms new land. It occurs on the new land that no life has ever been on.
Primary succession happens in a place where there is no soil and as a gradual growth of an ecosystem over a long period of time. Secondary succession occurs where there is already vegetation but has been destroyed by a natural disaster.
ecological succession
Primary succession happens in a place where there is no soil and as a gradual growth of an ecosystem over a long period of time. Secondary succession occurs where there is already vegetation but has been destroyed by a natural disaster.
primary succession
Primary succession occurs on ground which had no previous vegetation, including lava flows, bare rock and sand dunes. For example, newly created volcanic islandSecondary Succession follows the destruction or modification of existing vegetation, either naturally or by human activity. For example, section of a forest destroyed by fire.Ecosystems are constantly changing in response to natural and human disturbances. As an ecosystem changes, older inhabitants gradually die out and new organisms move in, causing further changes in the community.Primary Succession occurs on surfaces where no soil exists, And Secondary Succession follows a disturbance that destroys a community without destroying the soil.Primary succession is slow and secondary succession is rapid.Primary succession begins in areas where no soil is present.Secondary succession occurs in areas where there is soil already present.Ecological succession refers to orderly changes in an ecological community. These changes may happenbecause of the start of a new empty habitat (after a landslide, glacier, nuclear explosion, lava flow or even concreting), where all traces of previous biological material, even soil have been wiped out (Primary), orby some sort of disturbance (like bush fires, harvesting or logging) of an already existing habitat, which is not severe enough to kill everything. So plants can regrow and seeds spring up again (Secondary).Primary succession's the succession taking place at a venue where no ecosystems has ever existed (300 yrs) and secondary succession's a succession at a venue where an ecosystem was once established but deceased due to human impacts or natural disasters.Ecological succession refers to orderly changes in an ecological community.
