In which of the following both pairs have correct combination?

Options

  1. AGaseous nutrient cycle: Carbon and Sulphur; Sedimentary nutrient cycle: Nitrogen and Phosphorus
  2. BGaseous nutrient cycle: Nitrogen and Sulphur; Sedimentary nutrient cycle: Carbon and phosphorus
  3. CGaseous nutrient cycle: Sulphur and Phosphorus; Sedimentary nutrient cycle: Carbon and Nitrogen
  4. 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.
