Studying biochemical cycles in environmental science is significant because these cycles, such as the carbon and nitrogen cycles, regulate the flow of essential elements within ecosystems. They explain how nutrients are recycled, enabling plant and animal life to thrive. Understanding these processes helps predict the impacts of human activities, such as fossil fuel combustion and deforestation, on environmental sustainability. Moreover, insights gained from studying biochemical cycles can guide policymakers in implementing practices that promote resource conservation, restore ecosystems, and combat climate change.
