Atmosphere

The movement of nutrient elements through various components of an ecosystem is called as Nutrient cycling/ Biogeochemical cycling.

∙ Nutrient cycles are of two types- Gaseous and Sedimentary ∙

  The Reservoir for Gaseous type of nutrient cycle (Nitrogen and Carbon cycle) exists in the atmosphere.

∙ The reservoir for Sedimentary type of nutrient cycle ( Phosphorus and Sulphur cycle) is located in earth's crust.
