Upwelling is the movement of cool, nutrient-rich water from the bottom to the surface. This can occur due to various factors such as wind patterns, ocean currents, and topography of the ocean floor. Upwelling is important for marine ecosystems as it brings nutrients to the surface, supporting the growth of algae and other primary producers, which in turn support the entire food chain.
