What is biogeochemical cycling?

Biogeochemical cycling refers to the intricate movement and transformation of biological, geological, and chemical substances within and between ecosystems. This process encompasses the interactions between living organisms, such as plants and animals, and the non-living components of their environments, including soil, water, and minerals. Essential elements like carbon, nitrogen, phosphorus, and sulfur undergo constant cycling through various physical states, biological processes, and geological formations, ensuring the ongoing availability of these nutrients for all forms of life.

Understanding this concept highlights the connectivity within ecosystems, as different elements are utilized, transformed, and returned to the environment through various mechanisms such as decomposition, respiration, and photosynthesis. Biogeochemical cycles are fundamental to maintaining ecological balance and supporting life on Earth, illustrating the interdependence between organisms and their environment.
