Nutrient cycle - Wikipedia
https://en.wikipedia.org/wiki/Nutrient_cycle
WEBA nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.

Nutrient Cycles – Science, Technology, and Society
https://ecampusontario.pressbooks.pub/sciencesociety/chapter/chapter-5-flows-and-cycles-of-nutrients/
WEBNutrient cycling refers to the transfers, chemical transformations, and recycling of nutrients in ecosystems. A nutrient budget is a quantitative (numerical) estimate of the rates of nutrient input and output to and from an ecosystem, as well as the amounts present and transferred within the system.

WEBNutrient cycling. The cells of all organisms are made up primarily of six major elements that occur in similar proportions in all life-forms. These elements— hydrogen, oxygen, carbon, nitrogen, phosphorus, and sulfur —form the core protoplasm of organisms, and the first four of these elements make up about 99 percent of the mass of most cells.

https://www.khanacademy.org/science/biology/ecology/biogeochemical-cycles/a/the-nitrogen-cycle
WEBJun 9, 2016 · Nitrogen as a limiting nutrient. In natural ecosystems, many processes, such as primary production and decomposition, are limited by the available supply of nitrogen. In other words, nitrogen is often the limiting nutrient, the nutrient that's in shortest supply and thus limits the growth of organisms or populations.

WEBEnergy flows directionally through Earth’s ecosystems, typically entering in the form of sunlight and exiting in the form of heat. However, the chemical components that make up living organisms are different: they get recycled. What does that mean? For one thing, the atoms in your body are not brand new.

https://scienceaid.net/biology/ecology/nutrient.html
WEBA 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.
