The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Climax Community**: A climax community is the final stage of ecological succession. It is characterized by a stable and mature ecosystem that has reached a state of equilibrium. 2. **Ecological Succession**: This process involves a series of changes in the composition of a community over time. Initially, pioneer species such as lichens and mosses colonize an area, followed by intermediate species like ferns and shrubs, and finally leading to a climax community dominated by mature trees. 3. **Characteristics of Climax Community**: The climax community is stable and self-sustaining. It has a diverse range of species that are well-adapted to the local environment. This stability means that the community can maintain its structure and function over time, unless disrupted by external factors. 4. **State of Climax Community**: Since the climax community is stable and self-regulating, it is said to be in a state of equilibrium. This means that the populations of different species remain relatively constant over time, with small fluctuations. 5. **Conclusion**: Therefore, the climax community is in a state of equilibrium. **Final Answer**: The climax community is in a state of equilibrium. ---

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.
