Water and Life: Acquatic Ecosystems

As a source of life, water sustains an immense variety of life around and within it on Earth. 

Water based ecosystems are called aquatic ecosystems.

Saltwater and freshwater support entirely different ecosystems. There are multiple types of acquatic ecosystems on Earth.

Marine Ecosystems present in 71% of Earth's salwater i.e. oceans and sea.
