Biogeochemical cycles
In case of which one of the following biogeochemical cycles, the weathering of rocks is the main source of release of nutrient to enter the cycle?
D.Sulphur cycle
B.Nitrogen cycle
A.Carbon cycle
C.Phosphorus cycle
Correct Answer: Option C
In the phosphorus cycle, the weathering of rocks is the primary mechanism for releasing phosphorus into the environment.
Most of Earth's phosphorus is stored in rocks and sedimentary deposits.
Weathering, leaching, and mining release phosphorus from these sources.
Rain and weathering cause rocks to release phosphate ions and other minerals, which are then distributed in soils and water.
Statement c is correct.
