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.  

because the asteroid belt is between the mars and jupiter orbits, it is around 2.2 to 3.2 astronomical units (au) from the sun – which is approximately 329,115,316 to 478,713,186 km. the average distance between objects is a massive 600,000 miles.
