The primary role of nutrient cycling in ecosystems is to ensure the flow of essential nutrients, like nitrogen and phosphorus, through different biotic and abiotic components. This process supports plant growth and maintains soil fertility, which is critical for food production. Nutrient cycling facilitates the decomposition of organic matter, driving productivity and ecosystem resilience. It also promotes biodiversity by providing the necessary nutrients for diverse life forms. Understanding nutrient cycling helps in developing sustainable agricultural practices and conservation strategies that enhance ecosystem health, ensuring the long-term viability of natural and agricultural systems.
