The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Understand the Assertion The assertion states that "Biogeochemicals pass between non-living and living components of the biosphere in a cyclic manner." - **Explanation**: Biogeochemical cycles involve the movement of elements and compounds (like carbon, nitrogen, and water) through various parts of the ecosystem, including the atmosphere, lithosphere, hydrosphere, and biosphere. This process is indeed cyclic, as nutrients are reused and recycled within the ecosystem. ### Step 2: Understand the Reason The reason states that "Biogeochemicals are likely to exhaust one day." - **Explanation**: This statement implies that the biogeochemical cycles could eventually run out of essential nutrients. However, in reality, biogeochemical cycles are self-sustaining and do not exhaust the nutrients. While certain conditions can disrupt these cycles, the nutrients themselves are not likely to be exhausted permanently. ### Step 3: Evaluate the Truth of the Statements - The assertion is **true** because biogeochemical cycles do operate in a cyclic manner, facilitating the transfer of nutrients between living and non-living components. - The reason is **false** because biogeochemicals do not exhaust; they are continuously recycled through various processes in the ecosystem. ### Step 4: Conclusion Based on the evaluation: - The assertion is true. - The reason is false. Thus, the correct answer to the question is option C: Assertion is true, but reason is false. ---
