A coastal ecosystem is a dynamic environment where land meets the ocean. It includes various habitats such as beaches, estuaries, and mangroves. These areas are rich in biodiversity, supporting a wide range of plants and animals, including fish, birds, and marine mammals. Coastal ecosystems play a crucial role in protecting shorelines from erosion and providing resources for local communities. These ecosystems are influenced by both terrestrial and marine factors, making them unique. They serve as important nurseries for many marine species, including fish and crustaceans. Additionally, coastal ecosystems help filter pollutants and improve water quality, contributing to the overall health of the ocean.
