Biology Question on Eco-System
During the process of ecological succession, the changes that take place in communities are
orderly and sequential
random
very quick
not influenced by the physical environment
orderly and sequential
Solution
Biotic or ecological succession is the natural development of a series of biotic communities at the same site, one after the other till a climax community develops which does not change further because it is in perfect harmony with the environment of the area. The change is orderly and sequential. The first biotic community which develops in a bare area is called pioneer community. It has very little diversity. Climax community is a stable, self perpetuating and final biotic community. It develops at the end of biotic succession and is in complete equilibrium with the prevailing environment. The establishment of climax stage is called stabilisation.
