Which of the following pairs is a sedimentary type of biogeochemical cycle?

Explanation

Biogeochemical cycles are of two types: gaseous and sedimentary. In gaseous nutrient cycles, the materials involved in circulation between biotic and abiotic components of the biosphere are gases or vapors and the reservoir pool is the atmosphere or hydrosphere, e.g., carbon, hydrogen, oxygen, nitrogen, and water. In sedimentary nutrient cycles, materials involved in circulation between biotic and abiotic components of the biosphere are non­ gaseous and the reservoir pool is the lithosphere,e.g., phosphorus, calcium, and magnesium. Sulfur has both sedimentary and gaseous nutrient cycles.
