In ecology, allogenic succession is mediated by the abiotic components of the ecosystem, while the autogenic succession refers to the succession, which is mediated by the biotic components of an ecosystem.  

A volcanic eruption wiping out an entire island is an example of allogenic succession.  

A soybean crop helping in nitrogen fixation, leading to the development of other species is an illustration of autogenic succession.  

A tsunami devastating all the living organism in a habitat is an example of allogenic succession.  

Oak trees preventing the growth of smaller sun-seeking shrubs is an example of autogenic succession.

alexandr402 [8]

A. into a climax community; species replaces another

B. and replaces another; ecosystem becomes stable

C. on unoccupied ground; biological community replaces another

D. and then fails; niche changes

E. intraspecific competition; experiences interspecific competition

Answer:

C. on unoccupied ground; biological community replaces another

Explanation:

Primary succession  is a gradual change that occurs on bare rocks or areas that have no life existing on it before. It could take several years to be colonized by living things.  

On the other hand, secondary succession are changes that occur when one biological community replaces another as a result of factors such as wild fires, or take place in abandoned farm land. New species of organisms take over the area that has life existing on it already. Secondary succession occurs on areas or land that has been colonized initially before.
