It is a natural recycling system of mineral nutrients. The nitrogen cycle, the phosphorous cycle, the sulfur cycle, and the carbon cycle all involve assimilation of these nutrients into living things. These elements are transferred among living things through food webs, until organisms ultimately die and release them back into the geosphere. In biology, the nutrient cycle is a concept that describes how nutrients move from the physical environment into living organisms and subsequently are recycled back to the physical environment. This circular movement of nutrients is essential to any given ecosystem, and it must be balanced and stable for the system to be maintained.
Nutrient cycles allows the transfer of elements from one location to another.

Nutrient cycle is more often used in direct reference to the idea of an intra-system cycle, where an ecosystem functions as a unit. From a practical point, it does not make sense to assess a terrestrial ecosystem by considering the full column of air above it as well as the great depths of Earth below it. 2021-04-23 · Rainforest nutrient cycle.

The nutrient cycle is the key to all life on earth. While there are 6 main nutrient cycles, all of them depend on the same thing. The transfer of energy and matter from non-living chemicals to living organisms. All of the nutrients cycles share another key element. They all require microorganisms to properly function. Nutrients are chemicals necessary in any ecosystems for organisms to effectively grow, survive and Nutrient Cycle Definition.

The nutrient cycle describes how nutrients move from the physical environment into living organisms, and subsequently are recycled back to the physical environment. This movement of nutrients, essential for life, from the environment into plants and animals and back again, is a vital function of the ecology of any region. Generally, the coupling between nutrient cycles in mature forests is relatively tight; disturbances have the effect of decoupling pathways temporarily (Keiser et al., 2016). For example, nitrogen availability increases either due to mineralization in the event itself (e.g., fire) or decreased uptake, with the magnitude of the effect related to the severity of the disturbance ( Nave et al., 2011 ).

The cycling of three macronutrients are discussed below. The first is the carbon cycle. Plants acquire carbon through photosynthesis. The nitrogen and phosphorus cycles are also discussed, and plant acquire nitrogen and phosphorus as mineral nutrients from the soil. *nutrient cycle(*mineral cycle*)* A biogeochemical cycle , in which inorganic nutrients move through the soil, living organisms, air, and water, or through some of these (e.g. nitrogen as NO3 and NH4, etc.).
A perfect Nutrient Cycle/Biogeochemical Cycle is one in which nutrients are replaced as fast as they are utilised. Most gaseous cycles are generally considered as perfect cycles. In contrast sedimentary cycles are considered relatively imperfect, as some nutrients are lost from the cycle and get locked into sediments and so become unavailable for immediate cycling. The water cycle is important because water sustains all life on Earth. Through a series of evaporation, transpiration, condensation, precipitation, infiltration, runoff, and other smaller processes, the water cycle keeps the Earth's water c
