A seagrass bed is an underwater ecosystem formed by flowering plants known as seagrasses. These plants grow in shallow coastal waters and provide essential habitats for various marine life, including fish, crustaceans, and invertebrates. Seagrass beds play a crucial role in maintaining water quality by filtering pollutants and stabilizing sediments. In addition to supporting biodiversity, seagrass beds are vital for carbon sequestration, helping to mitigate climate change. They also serve as important feeding grounds for species like manatees and sea turtles. Overall, seagrass beds contribute significantly to the health of marine environments and coastal ecosystems.
