The primary function of nutrient cycling in ecosystems is to facilitate the transfer and transformation of essential elements like carbon, nitrogen, and phosphorus among organisms and the environment. This process helps maintain soil fertility, supports plant growth, and ensures the availability of nutrients for various life forms. Nutrient cycling also contributes to ecosystem stability and resilience by facilitating interactions among species. Disruptions in nutrient cycles can lead to problems such as ecosystem degradation, decreased productivity, and impaired ecological functions, highlighting the importance of maintaining balanced nutrient dynamics.
