As discussed in Nutrient Cycling -
Types of Nutrient cycle -
Nutrient cycles are of two types:
(a) gaseous and
(b) sedimentary.
- wherein
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.
Hence, the correct option is (a).
