=== Nutrient cycle ===
{{main|Nutrient cycle}}A [[nutrient cycle]] is a [[biogeochemical cycle]] involving the movement of inorganic matter through a combination of soil, organisms, air or water, where they are exchanged in organic matter.<ref name=":0">{{cite encyclopedia |last=Allaby |first=Michael |year=2015 |encyclopedia=A Dictionary of Ecology |title=Nutrient cycle |publisher=[[Oxford University Press]] |location=Oxford |edition=5th |url=https://www.oxfordreference.com/view/10.1093/acref/9780191793158.001.0001/acref-9780191793158-e-3868 |isbn=978-0-19-179315-8 |url-access=subscription}} {{subscription required}}</ref> Energy flow is a unidirectional and noncyclic pathway, whereas the movement of [[mineral nutrients]] is cyclic. Mineral cycles include the [[carbon cycle]], [[sulfur cycle]], [[nitrogen cycle]], [[water cycle]], [[phosphorus cycle]], and [[oxygen cycle]], among others that continually recycle along with other mineral nutrients into [[Productivity (ecology)|productive]] ecological nutrition.<ref name=":0" />

[[Biogeochemical cycle]]s that are performed by living organisms and natural processes are [[Water cycle|water]], [[Carbon cycle|carbon]], [[Nitrogen cycle|nitrogen]], [[Phosphorus cycle|phosphorus]], and [[sulfur cycle]]s.<ref>{{Cite web |title=Intro to biogeochemical cycles (article) |url=https://www.khanacademy.org/science/biology/ecology/biogeochemical-cycles/a/introduction-to-biogeochemical-cycles |access-date=2022-11-02 |website=Khan Academy |language=en}}</ref> Nutrient cycles allow these essential elements to return to the environment after being absorbed or consumed.<ref>{{cite web | url=https://bio.libretexts.org/Bookshelves/Botany/Botany_(Ha_Morrow_and_Algiers)/Unit_3%3A_Plant_Physiology_and_Regulation/15%3A_Nutrition_and_Soils/15.03%3A_Nutrient_Cycles#:~:text=Nutrient%20cycles%2C%20also%20known%20as,to%20plants%20and%20other%20organisms | title=4.3.3: Nutrient Cycles | date=29 May 2020 }}</ref> Without proper nutrient cycling, there would be risk of change in oxygen levels, climate, and ecosystem function.{{fact|date=November 2024}}
