B. If both Assertion and Reason are true and the Reason is not the corret explanation of the Assertion .
C. If Assertion is ture the Reason is false .
D. If both Assertion and Reason are false .

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that biogeochemical cycles pass between non-living and living components of the biosphere in a cyclic manner. This means that nutrients are continuously recycled through different forms and systems in the environment, involving both living organisms (like plants and animals) and non-living components (like soil, water, and air).

2. **Analyzing the Reason**: The reason provided states that biogeochemicals are likely to exhaust one day. This implies that the nutrients involved in these cycles could potentially run out or be depleted over time.

3. **Evaluating the Assertion**: The assertion is true because biogeochemical cycles (such as the carbon cycle, nitrogen cycle, and water cycle) indeed involve the transfer of nutrients between living organisms and their non-living environment. For example, plants absorb nutrients from the soil (non-living) and, when consumed by animals (living), these nutrients are passed through the food chain. Eventually, decomposers break down dead organisms, returning nutrients to the soil, thus completing the cycle.

4. **Evaluating the Reason**: The reason is false. While it is true that biogeochemical cycles can be disrupted due to human activities or environmental changes, the nutrients themselves do not exhaust in the same way that energy does. Nutrients are recycled and can exist in various forms, meaning they are not lost from the ecosystem.

5. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, and the reason is false.

### Final Answer:
- The assertion is true, and the reason is false.
