A coral reef near the Hawaiian islands is an example of a complex marine ecosystem.

Marine ecosystems are part of the earth's aquatic ecosystem. They include oceans, estuaries, salt marshes, lagoons, some tropical ecosystems, such as mangrove forests and coral reefs, rocky, subtidal ecosystems, and shores. The main difference between this and other aquatic ecosystems is its salt content larger than that of fresh water.

Such places are considered ecosystems because the plant life supports the animal life and vice-versa. See food chains
