Block+1+Fresh+Water

 Freshwater Freshwater : From outer space, Earth looks like our bodies with veins and organs. The organs represent the rivers and streams that channel water across the planet; everything from the smallest mountains to the biggest oceans! Salt water is 75% of earth and the portion of running fresh water only covers .3%. The  earth's freshwater biome and the amimals it supports are being threatened by pollution from farm runoff, industrial discharges, recreational boating, and fast food packaging. Because of the increasing pollution of the freshwater biome bottled water has become more popular than freshwater as a drink.

This zone is the warmest since it is shallow and can attract more of the sun's heat. There are many different species located here in this community. This can include several types of algae, aquatic plants, grazing snails, clams, insects, fishes, and amphibians. Larvae and eggs of insects such as dragonflies are found in the littoral zone. There is vegetation and animals living here that serve as food for reptiles such as turtles and snakes. Ducks can also feed very well here.

The surface water surrounded by the littoral zone is the //limnetic zone//. The limnetic zone is well-lighted and supports the life of plankton, both phytoplankton and zooplankton. Plankton are small organisms that mean a lot in the food chain. Without aquatic plankton, there would be few living organisms in the world, and certainly no humans. A variety of freshwater fish also swim in this zone.

Plankton do not live very long. When they die, they fall into the deep-water part of the lake/pond which is the //profundal zone//. This zone is much colder and muddier than the other two zones. Very little light gets all the way through the limnetic zone into the profundal zone. The fauna here are heterotrophs, meaning that they eat dead organisms and use oxygen for cellular respiration.

Some of the fish in the freshwater biome can adapt by the temperature, since it is cooler at the start of the stream than it is at the mouth of the river where it empties into another source. The water is also clearer, has higher oxygen levels, and freshwater fish such as trout can be found there.

Numerous aquatic green plants and algae can be found toward the mouth of the river or stream. There is a lot of sediment that has been picked up as the rivier moves toward the sea. This makes the water muddy, decreasing the light that can shine deep into the water. Since there is less light and lower oxegyn levels; this is the perfect place for fish such as catfish and carp. They do not require as much flora to survive.

They also have rivers ,streams,ponds, lakes and wetlands.The seasons are summer ,spring ,fall,and winter. During the summer, the temperature in the water is between 4° C to 22° C at the top. During the winter, the temperature at the bottom of the water can be 4° C while the top is 0° C (ice). In between the two layers, there is a thin zone called the thermocline where the temperature of the water changes very quickly. During the spring and fall seasons, there is a mixing of the top and bottom layers, usually the winds can change the temperature to around 4° C. This mixing also circulates oxygen throughout the lake. Of course there are many lakes and ponds that do not freeze during the winter.
