Detailed explanation-1: -The ways in which an element-or compound such as water-moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Detailed explanation-2: -Some examples of the biogeochemical cycles are the phosphorus cycle, oxygen cycle, carbon cycle and nitrogen cycle. Human activities have different impacts on the various biogeochemical cycles.

Detailed explanation-3: -The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.

Detailed explanation-4: -The three types of biogeochemical cycles are hydrological cycle, sedimentary cycle and gaseous cycle.

Detailed explanation-5: -The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. The biogeochemical cycles always have a state of equilibrium.
