Definition of marine ecosystem. "Marine ecosystems are within aquatic ecosystems. Including the oceans, seas, swamps, etc.. The marine environment is very stable when compared to terrestrial habitats or water sweet. The temperatures of the ocean masses vary only slightly, and salinity (3.5%). The ionic composition of seawater is similar to body fluids of most marine organisms, which solves the osmotic regulation. "

70% of the surface of the Earth is composed of marine ecosystems. These ecosystems play a role in regulating global climate, and allow coastal communities to develop sustainable economies.

The ecosystems are marine oceans, coral reefs, estuaries and coastal areas such as lagoons and seagrass beds. They are home to several species such as algae , marine mammals, fish and birds.

All marine salts are dissolved in water. The salts give water a salty taste, helps maintain species composition and the oceans when they are at zero degrees in winter.

Marine ecosystems provide humans with food and income. Confome support habitats for animals and plants that serve as fertilizer for crops and food additives and cosmetics. The coasts are protected from erosion of mangroves (trees and shrubs that grow in these habitats), coral reefs and seagrass beds. Marshes and estuaries have the ability to filter runoff from the land.
