Fresh Water Biome
The main characteristic of a fresh water area is that the salt concentration is under 1%. Further classified places for fresh water is either moving bodies of waters (lotic),or standing bodies on water (lentic). Moving bodies of water include rivers and streams. Standing bodies of water includes ponds, lakes and inland wetlands. Fresh water biomes are influenced by surrounding soil, climate and water currents and flow. Freshwater isn't as important as our oceans, if you read through the salt water page you will see what the ocean is important for. Some of those will apply for fresh water but there isn't much more to say about fresh water.
