Question

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

• A. Oxygen and nitrogen
• B. Phosphorus and sulphur
• C. Phosphorus and nitrogen
• D. Phosphorus and oxygen

Answer 1

The correct option is B Phosphorus and sulphur

Nutrient cycles are of two types: (a) gaseous and (b) sedimentary. The reservoir for gaseous type of nutrient cycle (e.g., nitrogen, carbon cycle) exists in the atmosphere and for the sedimentary cycle (e.g., sulphur and phosphorus cycle), the reservoir is located in Earth’s crust.
