The largest water ecosystem is the marine ecosystem, covering over 70 percent of the earth's surface. •Salinity = the amount of dissolved salts contained in the water. This paper reviews the types, extent, biodiversity and ecology of freshwater wetlands in the region, and documents the main threats to wetland ecosystems. The ocean zones based on light penetration are: photic and aphotic zone. An ecosystem is made up of the living organisms, the habitat they live in, the non-living structures present in the area, and how all of those relate to and influence each other. Each ecosystem and habitat on our planet has its own degree of variation of life; we call this biodiversity. Freshwater snails are also intermediate hosts of foodborne fluke infections affecting the liver, lungs and intestines of humans or animals. C.
