Option (E)
Explanation:
Phosphorous is an important nutrient that is found on earth. It acts as nutrients for the growth, development, and expansion of organisms like plants and animals. It is mostly found to be accumulated in the sedimentary rocks, which are formed from the compaction and solidification of sediments. This rocks when disintegrates due to the weathering and erosion, they mix up with the soil as well as water and transports from one place to another. Plants obtain these phosphatic ions directly from the soil.
Thus, the major reservoir for the phosphorous in the phosphorous cycle is the sedimentary rocks. From this only, the cycle of phosphorous initiates.
Hence, the correct answer is option (E).
The answer is a very good amount.....
