Explain how the biogeochemical cycles are essential for life.

Answer and explanation;Biogeochemical cycles are cycles or pathways through which a chemical element or a molecule circulates through the abiotic (non-living) ad biotic (living) components of an ecosystem.All chemical elements occurring in organisms are part of biogeochemical cycles. Carbon, hydrogen, oxygen and nitrogen are the key components in life of organisms. Therefore, the carbon, nitrogen, and oxygen cycles are the most important biogeochemical cycles.Biogeochemical cycles are essential for life and important to the ecosystems because matter on earth is limited in amount, and space for dead organisms as well. Additionally, biogeochemical cycles are important as as they transport and store these chemical elements so that they can be used by living organisms.

The correct answer would be b
