Water,Nitrogen, phosphorus and carbon are items that are cycled through the biosphere in biogeochemical cycles.
Explanation:
Biogeochemical cycles maintain the balance of elements and compound in nature.
These help the chemical substances to circulate through different spheres of the earth.
They are, water cycle, sulphur cycle Nitrogen cycle, Carbon cycle ,Phosphorus cycle etc.
If the biogeochemical cycles were not present then elements such as nitrogen , phosphorus carbon should have got completely used up instesad of getting replenished. Thus, making several metabolism stagnant.
