III and IV

D

I and IV

Answer

II and III

Explanation

Solution

Biogeochemical cycles can be grouped into 22 types: (i) Gaseous cycle: Material involved in circulation are gases or vapours and the reservoir pool is the atmosphere or hydrosphere, e.g., nitrogen, carbon, hydrogen, oxygen and water cycle. (ii) Sedimentary cycle : Materials involved in circulation are non-gaseous and the reservoir pool is lithosphere, e.g., phosphorus, sulphur, calcium and magnesium cycle.
