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.
