Question

What is biogeochemical cycles??

Answer 1

In geography and Earth science, abiogeochemical cycle or substance turnoveror cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere,atmosphere, and hydrosphere) compartments of Earth. There are biogeochemical cycles for carbon, oxygen, nitrogen, phosphorus, sulfur, and water; and there are human-induced cycles such as those for mercury and atrazine. In some cycles there are reservoirswhere a substance remains for a long period of time (such as an ocean or lake for water).

Answer 2

Biogeochemical cycles are the cyclic pathways in the living components of the ecosysytem moves from environment to organism and back to environment..e.g Nitrogen cycle and Carbon cycle
