Biogeochemical cycles<span> are named for the cycling of biological, geological and chemical elements through Earth and its atmosphere. The </span>cycles<span> move substances through the biosphere, lithosphere, atmosphere and hydrosphere. </span>Cycles<span> are gaseous and sedimentary. Gaseous </span>cycles<span> include nitrogen, oxygen, carbon and watre hope this helps</span>
<em><u>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.</u></em>
<u><em>All chemical elements occurring in organisms are part of biogeochemical cycles.</em></u> 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.
<em><u>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. </u></em>
<em><u>Additionally, biogeochemical cycles are important as as they transport and store these chemical elements so that they can be used by living organisms. </u></em>
