In Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. A cycle is a series of change which comes back to the starting point and which can be repeated. Water, for example, is always recycled through the water cycle, as shown in the diagram. The water undergoes evaporation, condensation, and precipitation, falling back to Earth. Elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another through biogeochemical cycles. The term "biogeochemical" tells us that biological, geological and chemical factors are all involved. The circulation of chemical nutrients like carbon, oxygen, nitrogen, phosphorus, calcium, and water etc. through the biological and physical world are known as biogeochemical cycles. In effect, the element is recycled, although in some cycles there may be places (called reservoirs) where the element is accumulated or held for a long period of time (such as an ocean or lake for water). Importance:- Biogeochemical cycles are important because they regulate the elements necessary for life on Earth by cycling them through the biological and physical aspects of the world. Biogeochemical cycles are a form of natural recycling that allows the continuous survival of ecosystems read less

Biogeochemical cycles are named for the cycling of biological, geological and chemical elements through Earth and its atmosphere. The cycles move substances through the biosphere, lithosphere, atmosphere and hydrosphere. Cycles are gaseous and sedimentary. Gaseous cycles include nitrogen, oxygen, carbon and water. These elements cycle through evaporation, absorption by plants and dispersion by wind. Sedimentary cycles include the leeching of minerals and salts from the Earth's crust, which then settle as sediment or rock before the cycle repeats. read less

A biogeochemical cycle is defined as the movement of elements, like those mentioned just a moment ago, through organisms and the environment. A way to remember this is to break apart the word 'biogeochemical' into pieces. The first part of the word, bio, involves biological organisms, like bacteria,...

A way to remember this is to break apart the word 'biogeochemical' into pieces. The first part of the word, bio, involves biological organisms, like bacteria, plants, and animals. The next part of the word, geo, involves geological processes, like weathering of rocks. The last part of the word indicates chemical processes, such as the formation of molecules. read less
