__ FRESHWATER AREAS __

__ Lakes and Pounds __ Two examples of fresh water areas are lakes and ponds. Even though lakes are deeper than ponds, ponds get more plants at the bottom. Why ponds get more plants, is because the pond is very shallow so sunlight can reach the bottom. __Marshes and Swamps__ A marsh is also a freshwater area. Marsh usually ranges from 1 to 6 feet deep. Marshes and swamps are sources of thick water with many living things in it. __ Rivers, Streams and Waterfalls __ In rivers and streams you will find fresh water that is constantly moving. Waterfalls are also another example. A water fall is usually in the middle of a river or at the end of a river, and it is when water goes over a cliff into the river again or the water goes into a lake. In many freshwater areas, some of the water is warm, while others are cold. __ FUN FACTS __ Freaswater ecosyestems are considerd the biological supermrkets. 2.6 of the worlds water is freashwater. 0.014% is the total volume of water avalible as soil mosture. Very few natural pollutients. Over 1500 pollutents for freashwater.

__Threats__ Sewege dumped in to water, fertalizer contaned in runoffs from farms and droghts are depleting or already low amont of freaswater. Due to pollutents killing oxygin amount in water many animals are dying.

PLANTS-

· Saw Grass · Cattails · ​ Pickle Weed · Water Lillys · Algae · Cranberries Plants are packed in freshwater swamps and ponds.

Although, most fresh water ranges in the summer at about 4 C at the bottom and 22 C at the top. In the winter the bottom is about 4 C and the top is 0 C or ice. The middle of the top and bottom layers changes rapidly throughout the year. The temperature is normaly cooler at the source than at the mouth of the biome. Most freshwater biomes are in humid areas. If the freshwater biome was not in a humid area, the water source (river, stream, etc.) would react differently.
