Physical Features

 Freshwater is obviously, any water that does not contain salt. And a biome is a community characterized by its plant and animal life (dictionary.com, par 1). The two together create a freshwater biome. A freshwater body of water has to have less then 1% salinity content to be considered freshwater (Freshwater Biome, par 1). Freshwater biomes can be any of the following; ponds and lakes, streams and rivers, and wetlands (Freshwater Biome, par 2,7,8)


Plant Life

The plant life in freshwater biomes can be very diverse depending on the body of water. The plant life can be found in many different parts of the body of water; floating at the top or attached into the ground at the bottom.  Located at the top of most ponds is a film of green algae. You might see cattails sticking out of most ponds along with watercress and various other types of plants. (Mithra, par 1) In wetlands there can be found a lot of plant life. Like ponds, wetlands have cattails but they also have pondlilies, black spruce, and more. (Freshwater Biome, par 8)

Threats

The main threat to freshwater biomes is pollution. Runoff is the main purposse for this pollution. Things like fertilizers and waste dumpings get into the freshwater biomes and cause rapid growth of algae. The algae can suffocate all of the other organism living in the water because the algae films the top not letting any sunlight in. Also, the pollution itslef can directly kill any organisms living in the freshwater biomes (World's Biomes, par 7).
