Assertion:- Biotic components are as important as abiotic components for determination of habitats in various ecosystems.
Reason:- Interaction between biotic component and physico-chemical components determine the specific regional and local variations of biome.

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

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that biotic components (living organisms) are as important as abiotic components (non-living elements) in determining habitats in various ecosystems. This means that both types of components play a crucial role in shaping the environment where organisms live.

2. **Understanding the Reason**: The reason provided explains that the interaction between biotic components (like plants, animals, and microorganisms) and abiotic components (such as temperature, water, light, and soil) leads to specific regional and local variations in biomes. This highlights the interconnectedness of living and non-living factors in shaping ecosystems.

3. **Analyzing the Relationship**: The assertion and reason are closely related. The assertion emphasizes the equal importance of biotic and abiotic components, while the reason elaborates on how their interaction results in diverse ecosystems. This suggests that without one, the other cannot effectively contribute to the formation of habitats.

4. **Evaluating the Truth of Statements**:
- The assertion is true because both biotic and abiotic components are essential for the existence and functioning of ecosystems.
- The reason is also true as it accurately describes how the interaction between these components leads to variations in ecosystems.

5. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, we can conclude that the correct answer is that both statements are true and the reason is a correct explanation of the assertion.

### Final Answer:
Both the assertion and reason are true, and the reason is a correct explanation for the assertion.
