In Earth science, a biogeochemical cycle or substance turnover or cycling of
substances is a pathway by which a chemical substance moves through both
... by the chemical part. There are four biogeochemical cycles, and each of them
returns to the earth important elements that are required in living organisms.
Some of the major biogeochemical cycles are as follows: (1) Water Cycle or
Hydrologic Cycle (2) Carbon-Cycle (3) Nitrogen Cycle (4) Oxygen Cycle.
The four biogeochemical cycles include the water cycle, the carbon cycle, the
phosphorous cycle and the nitrogen cycle. These four cycles involve biology, ...
