*nutrient cycle(*mineral cycle*)* A biogeochemical cycle [1], 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.).

Extension Questions. 28. Plants and animals are part of all of the nutrient cycles through the foods they eat and what eats them (food chains and food webs). Name the four classes of organic compounds (containing . carbon) and explain how the carbon cycle and nitrogen cycle contribute to the usable supplies of these 8.7 Nutrient cycles (ESGBC) A nutrient cycle refers to the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by the food web pathways previously presented, which decompose organic matter into inorganic nutrients.

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.

A nutrient cycle is the perpetual movement of nutrients from the physical environment into a living organism and then recycled back into the physical environment. The health and stability of any ecosystems and the organisms that exist within it is highly dependent on a balanced and table nutrient cycle.

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 ).
