Question

Volcano eruption disturbs

• A. Phosphorus cycle
• B. Nitrogen cycle
• C. Carbon cycle
• D. Sulphur cycle

Answer 1

Answer: (A)

Phosphorus cycle

Phosphorus is a critical element. It is obtained from soil as orthophosphates. Organic phosphorus circulates in nature from plants to animals. Phosphate is released by decomposers back to the soil. The reservoir pool for phosphorus is phosphates in rocks from which the phosphorus is slowly transferred to cycling pool. Volcanic eruptions disturb the rock structure and composition. New rocks may be formed by solidification of molten magma and older rocks may get covered by new layers of lithosphere. This disturbs the phosphorus cycle.
