Q46 / 180 · NEET 2015 (Phase 2) · Botany

In which of the following both pairs have correct combination?

  • A
    Gaseous nutrient cycle: Carbon and Sulphur; Sedimentary nutrient cycle: Nitrogen and Phosphorus
  • B
    Gaseous nutrient cycle: Nitrogen and Sulphur; Sedimentary nutrient cycle: Carbon and phosphorus
  • C
    Gaseous nutrient cycle: Sulphur and Phosphorus; Sedimentary nutrient cycle: Carbon and Nitrogen
  • Correct answer
    D
    Gaseous nutrient cycle: Carbon and Nitrogen; Sedimentary nutrient cycle: Sulphur and phosphorus

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.

Hence, the correct answer is option: 'D'.
