What is the difference between primary succession and secondary succession.?

Answer 1

Primary succession occurs on ground which had no previous vegetation, including lava flows, bare rock and sand dunes. For example, newly created volcanic island

Secondary 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.

1. Primary succession begins in areas where no soil is present.
2. Secondary succession occurs in areas where there is soil already present.

Ecological succession refers to orderly changes in an ecological community. These changes may happen

1. because 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), or
2. by 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. These changes may happen

1. Because 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), or
2. By 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)

Answer 3

There are seven differences between primary and secondary succession. Some of the major ones are that secondary succession is faster than a primary succession and primary succession begins where there is no soil present.

Answer 4

Primary succession occurs on newly formed land such as a volcano. No organic content and organisms are present at the beginning. It is a relatively slow process.

Secondary succession occurs on previously occupied land such as an area that has been devastated by a forest fire. Soil with organic content is found on this piece of land and organisms may be present at the beginning. This process is faster than primary succession.
