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 .
