The correct Answer is:
To solve the question, we need to evaluate the two statements regarding phosphorus reservoirs and their absorption by plants. ### Step-by-Step Solution: 1. **Evaluate Statement 1:** - The statement claims that the major reservoirs of phosphorus are phosphate rocks and fossil bone deposits laid down in the past geological ages. - Phosphate rocks are indeed known to be a primary reservoir of phosphorus. They contain significant amounts of phosphates. - Fossil bone deposits also contain phosphorus, as they are composed of organic materials that include phosphates (like bones and teeth). - **Conclusion:** Statement 1 is correct. 2. **Evaluate Statement 2:** - The statement asserts that during the weathering of rocks, minute amounts of these phosphates dissolve in soil solution and are absorbed by the roots of the plants. - When rocks weather, they release phosphates into the soil. These dissolved phosphates are available for plant uptake through their roots. - This process is essential for the phosphorus cycle in terrestrial ecosystems. - **Conclusion:** Statement 2 is also correct. 3. **Select the Correct Option:** - Since both statements are correct, we look at the options provided: - A. Both statements 1 and 2 are correct. - B. Statement 1 is correct but statement 2 is incorrect. - C. Statement 1 is incorrect but statement 2 is correct. - D. Both statements 1 and 2 are incorrect. - The correct option is **A. Both statements 1 and 2 are correct.** ### Final Answer: **A. Both statements 1 and 2 are correct.**
