Which biogeochemical cycle is least dependent on biotic processes?

Question 8 options:

carbon

nitrogen

phosphorus

water

Phosphorus biogeochemical cycle is least dependent on biotic processes

Explanation:

The slowest biogeochemical cycle, the phosphorus cycle doesn't have a constant stability in the atmosphere unlike other biogeochemical cycles. Other cycles include - Carbon cycle, nitrogen cycle, water cycle etc.

Phosphorus has it's cycle through the soil, water and sediment biotic factors. It persists in a small amount in the atmosphere and it has a liquid state in room temperature. It is a limited cycle for plants and animals.
