Marine Ecosystems

Marine ecosystems are systems of living organisms interacting with their oceanic and coastal environment, including plants, animals, microbes, and physical components such as water, sediments, and nutrients. They are shaped by both external factors, such as currents, temperature, and climate, and internal processes, including predation and nutrient cycling. Marine ecosystems provide services to humans, including fisheries, coastal protection, and carbon storage, and can be affected by human impacts and climate change.
