The correct answer is: Phosphorus cycle
Biogeochemical cycles are of two types:
(a) Gaseous: Biogenetic materials involved in circulation are gases eg. N2,O2,CO2 etc.
(b) Sedimentary: Biogenetic materials involved in circulation are non-gaseous eg. P2, Ca, S, etc forms rocks.

The flow chart represents the phosphorus biogeochemical cycle occurring in a terrestrial ecosystem. The phosphorus cycle is a sedimentary cycle and its reservoir pool is lithosphere.
