Biogeochemical cycling is the process by which elements such as carbon, nitrogen, phosphorus, and other nutrients are transferred between living organisms, the atmosphere, the soil, and water bodies in the environment. This cycling is essential for the functioning of ecosystems, as it involves the uptake, utilization, release, and recycling of these essential elements. Biogeochemical cycling plays a crucial role in regulating the availability of nutrients for organisms, as well as in the global climate system through processes such as the carbon and nitrogen cycles. Researchers study biogeochemical cycling to better understand how these processes contribute to ecosystem functioning and how they may be impacted by human activities such as deforestation, agriculture, and climate change.
