Marine ecosystems
Marine Ecosystems
Marine Ecosystems (pronunciation: /məˈriːn ˈiːkəʊˌsɪstəm/) are the largest of Earth's aquatic ecosystems and are distinguished by waters that have a high salt content. These systems contrast with Freshwater Ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and include Oceans, Coral Reefs, and Estuaries. Marine ecosystems are very important for the overall health of both marine and terrestrial environments.
Etymology
The term "Marine" comes from the Latin marinus meaning "of the sea" and "Ecosystem" is derived from the Greek words oikos meaning "house" and systema meaning "system". Thus, "Marine Ecosystem" can be interpreted as the system of the sea.
