Made of saline water, 72% of the Earths water is made up of salt water The ocean currents can greatly affect the Earth's climate by transferring heat. Decomposers include seaweeds and crustaceans. The biodiversity is very high in the coastal environments of the marine ecosystem. However, in some places of the ocean such as very deep sea, the knowledge of biodiversity is limited because of the lack of information. The average temperature of the marine ecosystem is around 39 degrees Celcius. Marine Ecosystem has a diverse variety of habitats from deep sea to near shore. Different physical features affect habitats such as temperature, salinity level, wind, location etc. Communities include several species interacting with each other Abiotic factors are: Temperature, salinity, Ph level, tides, winds and sediments etc. Biotic Factors are: Plants, crustaceans, mollusks, fish, mammals etc.
