Question

Which one is a sedimentary cycle.?
A.) Oxygen cycle
B.) Nitrogen cycle
C.) Hydrogen cycle
D.) Phosphorus cycle
E.) Carbon cycle

Answer 1

Certain cycles exist in nature that involve the flow of nutrients which are sediment released from rocks that get mixed with water. In this way, this substance enters the living system. Nutrient flow is essential for all living organisms.

Complete answer:
We can say that the correct answer is the option “D”, Phosphorus Cycle. Normally, rocks also become older like human beings and the upper crust of the rocks acquires a layer called sediment. The sediment is a composition of several minerals such as Phosphorus. We all know that the phosphorus is stored in large quantities in sediments formed by the rocks.
We are trying to answer why the Phosphorus cycle is called a sedimentary cycle and the reasons are offered as follows:

1. The planet’s Lithosphere consists of hard rocks and soil. The hard rocks and soil release sediment formed on the loose upper crust of the rocks or the soil. This process is called sedimentation.
2. Sedimentation takes place along with the aging of rocks. The phosphorus helps in increasing the yield of the crops, lack of phosphorus can result in a decreased yield of the crops.
3. The phosphorus cycle consists of the movement of phosphorus from rocks to soil and water. It transfers from water to sediment.
4. The bacteria present on earth and plants release phosphorus and which is deposited in nature.
5. When water flows over the rocks and the soil, the sediment gets mixed with and flows to different places. Phosphorus contained in the washed away sediments gets mixed with water and forms deposits. Normally phosphorus is prepared by leaving decaying plants and other organisms in fields; whenever the quantity is insufficient the additional quantity is supplied in the form of manure.

Hence, the correct answer is option (D)

Note: Students can remember this fact about the phosphorus cycle better by remembering the fact about the process of the sedimentary cycle. Sedimentary cycles refer to the bundles of phosphorus which is deposited in some places when the loose sediment from rocks gets washed away.
