Freshwater Biome

Freshwater is a biome that has water with a low salt concentration — usually less than 1%. There are several types of freshwater biomes.  These include ponds, lakes, streams, rivers and wetlands.  Animals and plants that live in freshwater biomes have cells that have adjusted to the low salt amount in the water.
