Options

A. Sulphur cycle
B. Phosphorus cycle
C. Nitrogen cycel
D. Carbon cycle

Answer

B

Explanation

Phosphorus cycle is a sedimentary biogeochemical cycle. It describes the movement of phosphorus throgh the lithosphere, hydrosphere and biosphere and the main reservor pool is lithosphere.
Atmosphere does not play any significant role in the movement ofsphosphorus because phosphorus and phosphorus based compound are usually solids at the typical ranges of temperature nd pressure found on earth . The production of phosphine gas occurs only in specialised , local conditions .
