Question

what is the importance of different biochemical cycles in nature

Answer 1

They are the essential drivers of environmental processes as they regulate the levels of elements essential for life among different pools. Alterations in biogeochemical cycles, such as human induced rapid increase of the concentration of certain elements in the atmosphere, may change the proportion of these elements in particular pools, by making them too scarce or too abundant. Excess element in a particular pool may involve levels that are poisonous for life or critical changes to environmental processes. All biogeochemical cycles are interlinked with each other to some extent, and cycles may affect environmental conditions at global scales (particularly when atmospheric pools are involved), as well as at local scales.
