ocean nutrient cycling
Ocean nutrient cycling is the process by which essential elements like nitrogen, phosphorus, and carbon move through the marine ecosystem. Organisms such as bacteria and phytoplankton absorb nutrients for growth. When they die or produce waste, these nutrients are released back into the water, making them available for other marine life. Physical processes like water currents, storms, and upwelling help distribute nutrients throughout different ocean layers, supporting a balanced ecosystem. This cycle sustains marine life, influences climate regulation, and maintains the health of the ocean environment.
