Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be ...
The Earth's land surface is divided into eight terrestrial biogeographic realms or ecozones, which contain hundreds of smaller ecoregions. Ecoregions are classified into biomes or major habitat types, which have similar climates and vegetation types. The freshwater system is similar, with ecoregions classified into freshwater realms and biomes.
Freshwater organisms are generally divided into the categories of benthic and pelagic organisms, as these are the two zones of life found in the freshwater biome. Freshwater organism can include invertebrates , insects , fish , amphibians , mammals , birds , aquatic plants , and planktons .

Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always potable water, that is, water safe to drink by humans. Much of the earth's fresh water (on the surface and groundwater) is to a substantial degree unsuitable for human consumption without treatment.
The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva.Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae).
This is a list of freshwater ecoregions in Latin America and the Caribbean, as identified by the World Wildlife Fund (WWF). The WWF divides the Earth's land surface into ecoregions, defined as "large area[s] of land or water containing a distinct assemblage of natural communities and species". Ecoregions are grouped into complexes and ...
Freshwater swamp forests, or flooded forests, are forests which are inundated with freshwater, either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones, from boreal through temperate [1] and subtropical to tropical. [2]
