A Primary group is a group characterized by intimate, long term, face to face association and cooperation. Allogenic type of succession refers to the succession in response to the changes in the external environment.When the community itself changes its physical environment, that is called as autogenic succession. The chief difference between primary and secondary succession is that: Primary succession begins with no life or soil, while secondary succession begins with both. Subsequently microorganisms in the soil feed on leaves and fungi. Primary succession stars with bare land and lichen and starts to build a community. Small gaps stimulate more shade tolerant species to grow whereas large gaps favors suppressed seedling growth and invading opportunistic to grow.Furthermore, extensive land clearing and fire can result in severe damage to the vegetation that already exist and therefore completely different community can be established in the gap/area created by such devastation. What is the difference between primary succession and secondary succession? A secondary group is larger than a primary group, relatively temporary, more anonymous, formal, and impersonal. primary succession occurs when a species moves into an area that starts as bare rock primary succession involves repopulating a previously damaged ecosystem secondary succession begins with the entrance of … Gaps can be either small scale or large scale.

Biological actions on the environment (is included as degradative succession as) is a type of autogenic succession.Fallen leaves are first colonized by fungi. What is one difference between primary and secondary succession Secondary succession behings on soil and primary sucession begin a newly exposed surface A tropical rain forest may not return to it's orginal climax community, after which of following substances When the organic substrate is completely metabolized degradative succession terminates.Primary Succession is an ecological succession that takes place following an opening of uninhabited, infertile habitat, or it can also occur in an environment that is devoid of vegetation and usually lacking topsoil. There are two main types of succession namely, primary succession and secondary succession. Secondary succession is where the community is already there but has been destroyed. Due to the secretion of enzymes by fungi, leaves get digested and soften.
