This nutrient is cycled between living things and the soil. plants absorb this nutrient from the soil and turn it into organic compounds through assimilation. animals eats the plants and pass the nutrient through the food chain from one organism to another. when the animal dies, it decomposes and returns the nutrient back to the soil. the nutrient can also enter the soil through weathering and erosion. which cycle is being described?
a. water cycle
b. carbon cycle
c. nitrogen cycle
d. phosphorous cycle

The correct answer will be option-D.

Explanation:

The phosphorus cycle is a description of the movement of the phosphorus in a cycle between the rocks to the soil to sediments and the organisms.

The phosphorus is added to the soil in the form of phosphate ions through mechanical and chemical weathering, raining, erosion and leaching. This is then distributed to the soil and water which gets absorbed by the organisms.

The phosphorus acts as a macro-nutrient in the organism as it is the component of the bio-molecules. After the death of the organism, the decomposition process returns this element back to the soil.

Thus, option-D is the correct answer.
