Nutrient cycling is the process by which essential nutrients are exchanged and recycled between living organisms and their environment. This process is critical for the functioning and sustainability of ecosystems, as it allows for the replenishment of nutrients necessary for the growth and survival of organisms. The specialized skill of nutrient cycling involves understanding the complex interactions and processes involved in the movement of nutrients through various biotic and abiotic components of an ecosystem. Effective management of nutrient cycling is crucial for sustainable agriculture, forestry, and conservation of natural resources.
