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.

Options

A. If both Assertion &Reason are true and the reason is the corect explanation of the assertion , then mark (1)
B. If both Assertion & Reason are true but the reason, is not the correct explanation of the assertion , then mark (2)
C. If Assertion is true statement but Reason is false , them mark (3).
D. If both Asseration and Reason are false statements , then mark (4).

Answer

To analyze the given statements regarding the climax community in ecological succession, we will break down the assertion (A) and reason (R) step by step.

### Step-by-Step Solution:

1. **Understanding Succession**:
- Succession is the process through which ecosystems develop over time, starting from a barren or disturbed area to a more stable and mature community known as the climax community.
- During this process, various species colonize the area in a specific sequence, leading to increased biodiversity.

2. **Climax Community**:
- The climax community represents a stable and mature ecosystem where species composition remains relatively unchanged over time unless disrupted by external factors.
- It is characterized by a balance between the biotic (living organisms) and abiotic (environmental) components.

3. **Assertion Analysis (A)**:
- The assertion states that "neither the community modifies the environment nor the environment forces the community to leave the place in the climax stage of succession."
- This is true because, in a climax community, the ecosystem reaches a state of equilibrium. The species present are well-adapted to the environment, and there is no significant change in species composition unless a disturbance occurs.

4. **Reason Analysis (R)**:
- The reason states that "the climax community is xerophytic in most types of succession."
- This statement is false because a climax community can be found in various environments, not just xerophytic (dry) conditions. Climax communities can be mesophytic (moderate moisture) or hydrophytic (wet), depending on the climatic and environmental conditions.

5. **Conclusion**:
- Since the assertion (A) is true and the reason (R) is false, we conclude that the assertion is correct while the reason is incorrect.

### Final Answer:
- Assertion (A) is true.
- Reason (R) is false.
