Freshwater ecosystems
Fresh water is essential to the maintenance of both aquatic and terrestrial life, including man, although only about 1 per cent of water on the earth is fresh water. It differs from sea water in its salinity value, which is the number of grams of salts of sodium, potassium, calcium, magnesium, chloride, sulphide, carbonate and bromide dissolved in 1 kilogram of water. Freshwater ecosystems are divided into two systems, lentic (still water) and lotic (running water).
