In which of the following both pairs have correct combination?
Options
- AGaseous nutrient cycle: Carbon and Sulphur; Sedimentary nutrient cycle: Nitrogen and Phosphorus
- BGaseous nutrient cycle: Nitrogen and Sulphur; Sedimentary nutrient cycle: Carbon and phosphorus
- CGaseous nutrient cycle: Sulphur and Phosphorus; Sedimentary nutrient cycle: Carbon and Nitrogen
- DGaseous nutrient cycle: Carbon and Nitrogen; Sedimentary nutrient cycle: Sulphur and phosphorus
Correct answer
D. Gaseous nutrient cycle: Carbon and Nitrogen; Sedimentary nutrient cycle: Sulphur and phosphorus
Step-by-step solution
TYPES OF BIOGEOCHEMICAL CYCLES:
i) Gaseous cycle:
- The exchange of nutrients occurs in gaseous or vapour form.
- Biogeochemical is non–mineral.
- The reservoir pool is atmosphere or hydrosphere.
- e.g. Nitrogen, carbon, oxygen, and hydrogen cycle.
ii) Sedimentary cycle:
- Biogeochemical is mineral.
- Reservoir pool is the earth’s crust or lithosphere.
- e.g. sulphur and phosphorous cycle.
