Studying chemical cycles in ecosystems is significant because these cycles, including the carbon, nitrogen, and phosphorus cycles, maintain the balance of nutrients essential for life. They describe how substances move through living organisms and the environment, influencing biodiversity and ecosystem health. Understanding these cycles helps predict responses to disturbances, such as pollution and climate change. Knowledge of chemical cycles is fundamental for managing resources sustainably and ensuring the resilience of ecosystems in the face of anthropogenic pressures.
