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

Options

A. If both Assertion `&` Reason are True `&` the Reason is a correct explanation of the Assertion.
B. If both Assertion `&` Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason if False.
D. If both Assertion `&` Reason are false.

Answer

To solve the assertion and reason question, we will analyze both statements and determine their validity and relationship.

### Step 1: Analyze the Assertion
The assertion states: "Climax community is in near equilibrium with the environment."
- A climax community is a stable and mature ecological community that has reached a stage of ecological succession. It is characterized by a stable structure and composition that is well-adapted to the prevailing environmental conditions. Therefore, this assertion is true.

### Step 2: Analyze the Reason
The reason states: "Composition and structure of climax community generally show change with changing environment."
- While the climax community is stable, it is also true that it can respond to changes in the environment. This means that if there are significant changes in environmental conditions (like climate, soil, etc.), the composition and structure of the climax community may also change. Thus, this reason is also true.

### Step 3: Determine the Relationship
Now we need to determine if the reason provides a correct explanation for the assertion.
- The assertion indicates that the climax community is in equilibrium with the environment, while the reason explains that changes in the environment can lead to changes in the community. This relationship suggests that the equilibrium is dynamic; the community can adjust to maintain stability despite environmental changes. Hence, the reason does correctly explain the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer
The correct answer is: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
