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.  

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
