Detailed explanation-1: -Sedimentary cycle-The reservoir exists in the earth’s crust. Examples: Sulphur, phosphorus, calcium, etc.

Detailed explanation-2: -The sulphur cycle has both gaseous and sedimentary phases. Sedimentary cycle also includes iron and calcium cycles. Thus, the correct answer is option (D) Sulphur.

Detailed explanation-3: -Sedimentary cycles include iron, calcium, phosphorus, sulfur, and other earthbound elements. As the carbon, hydrogen, nitrogen movement takes place by the atmosphere but phosphorus movement takes place by the lithosphere, hydrosphere, and biosphere.

Detailed explanation-4: -The phosphorus cycle is a sedimentary cycle (unlike carbon, oxygen, and nitrogen), the atmosphere is not a reservoir for phosphorous nor do microorganisms fix phosphorus as they do nitrogen. Phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots.

Detailed explanation-5: -The phosphorus cycle is also a type of sedimentary cycle. It is due to the sedimentary rocks, also because the cycling of phosphorus from the abiotic to the biotic and back will occur due to the other sort of rocks on weathering. Phosphorus is a significant supplement for plants and creatures.
