Question

______________ is without gases phase

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

Answer 1

Answer:

C. Phosphorus cycle

• Unlike other biogeochemical cycles such as the carbon and nitrogen cycles, phosphorus does not form significant gaseous compounds and does not circulate through the atmosphere as a gas.

• The movement of phosphorus in the environment is mainly through rocks, soil, water, and living organisms—none involves a gas phase.
