What is the purpose of the biogeochemical cycles? a to cycle energy through a food chain b to recycle matter through the biosphere c to recycle rocks through the layers of earth d to cycle nutrients through the human body

B to recycle matter through the biosphere

Explanation:

The biogeochemical cycle describes how elements and compounds moves between the living and non-living component of the biosphere.

The cycle shows how matter which are composed of elements and compounds moves through various part of our world. In short, the cycle constantly proves that no matter is lost or destroyed. They are actually recycled. Elements such as hydrogen, oxygen, phosphorus, carbon, nitrogen are constantly being recycled as no new ones are formed. The biogeochemical cycle provides a vivid explanation as to why this occurs.
