Fun Freshwater facts:
Freshwater lakes
Lakes are part of the freshwater biome, which typically range in size from as little as a few square yards up to thousands of square miles. Lakes can be divided into three different“ zones”.
1. The littoral zone is located near the shores of lakes and ponds and is home to algae, snails, insects, crustaceans and amphibians. It is the warmest of the zones since it shallow and can absorb the sun’ s heat.
2. The limnetic zone is situated near the surface in the open water and is populated by plankton, small organisms, and freshwater fish.
3. The profundal zone includes the deepest waters of lakes and ponds, and is much cooler and denser than the other two zones.
Fun Freshwater facts:
• Freshwater covers 0.8 % of aquatic ecosystems
• 797 % of all surface water is in oceans
• Great lakes in north America and Lake Baikal in Russia, containing 7 / 8 of this fresh water surface
• The Baikal is home of more than 2,500 species of plants and animals, 2 / 3 which can be found nowhere else in the world
• Fresh water is naturally occurring water on Earth ' s surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams.
• Lake Eyre is the largest freshwater lake in Australia
• There are over 700 different species of fish that live in a freshwater biome.
• The water in a freshwater biome contains less than 1 % of salt water. Any body of water that contains little to no salt is considered freshwater.
