Nitrogen Cycles Project: 2. Biogeochemical Cycle (860 words) |
 | The term biogeochemical cycles expresses the interactions among the organic (bio-) and inorganic (geo-) worlds, and focuses on the chemistry (chemical-), and movement (cycles) of chemical elements and compounds. |
 | In studying biogeochemical cycles, it is important to express in a common unit the amount of each element in all its phases and all its chemical compounds. |

| Biogeochemical cycle - Wikipedia, the free encyclopedia (844 words) |
 | In ecology and Earth science, a biogeochemical cycle is a circuit or pathway by which a chemical element or molecule moves through both biotic ("bio-") and abiotic ("geo-") compartments of an ecosystem. |
 | The most well-known and important biogeochemical cycles, for example, include the carbon cycle, the nitrogen cycle, the oxygen cycle, the phosphorus cycle, and the water cycle. |
 | Biogeochemical cycles always involve equilibrium states: a balance in the cycling of the element between compartments. |
