Select the pairs of sediamentary biogeochemical cycles.
I. Hydrogen cycle and water cycle
II. Phosphorus cycle and sulphur cycle
III. Calcium cycle and magnesium cycle
IV. Carbon cycle and nitrogen cycle

Options

A. I and II
B. II and III
C. III and IV
D. I and IV

Answer

B

Explanation

Biogeochemical cycles can be grouped into 2 types:
(i) Gaseous cycle: Material involved incirculation are gases or vapours and the reservoir pool is the atmosphere or hydrosphere, e.g., nitrogen, carbon, hydrogen, oxygen and water cycle.
(ii) Sedimenatry cycle : Materials involved in circulation are non-gaseous and the reservoir pool is lithosphere, e.g., phosphrorus, sulphur, calcium and magnesium cycle.
