Climax communities

Climax communities

Assertion: Climax community is in near equilibrium with the environment Reason: Composition and structure of climax community generally show change with changing environment

Assertion: Secondary succession always involves a predictable sequence of species and ends up with the same climax community as existed prior to the disturbance. Reason: A pond cannot be considered as a self sustained ecosystem as it does not possess all the structural and functional components which work as a unit in an ecosystem.

[A] : The community that ends in a succession is known as climax community . [R] : For a species population in climax community to be stable , there must be a balance between natality and mortality .

In plant succession, when climax community is reached, the net productivity

In plant succession, when climax community is reached, the net productivity?

[A] : Every biological system resists a change and wants to remain in a state of equilibrium . [R] : Climax communities of an ecosystem are produced after several changes it has gone through succession .

Starting from the pioneer species, trace the sequence that follows in an ecological succession on a bare rock, until climax community is reached in an ecosystem. Name this type of succession.

A: Neither the community modifies environment nor the environment forces the community to leave the palce in climax stage of succession. R: Climax community is xerophytic in most of the types of succession.
