2. Freshwater - water that is not salty especially when considered as a natural resource
Biome - a major ecosystem spread over a wide geographic area, and characterized by certain types of flora and fauna.

4. Elevation The elevation in freshwater varies.
Elevation greatly depends on location.
Most freshwater elevations range from 20,000 ft. – 1,500 ft.

5. Geology Waves Tides Currents Salinity Temperature light intensity
nutrient concentration

6. Climate/Temperature Tropical to low temperate climate zones
Summer: 22C, 71.6F
Winter: 4C, 39.2F
Temperature in water decreases with depth.
Freshwater biomes contain very little salt.

7. Rainfall/Snowfall
Average water rainfall: inches per year

8. Seasonality
Freshwater has semitropical climates (freezing never occurs)
Summer: wet seasons
Winter: dry seasons
Freshwater biomes have hurricane seasons
Occurs during the summer and early fall

9. Winds (Wind patterns in Summer and Fall)
(Wind patterns in Winter and Spring)

10. Animals
It is believed that more than 700 species of fish, 1,200 species of amphibians, mollusks, and insects all live in these areas.

13. Plants spike rush bull rush pickerel weed cattail water lily
mangrove leaves.

14. Indigenous People Frogs Crabs Shrimp Turtles Tadpoles Bass Salmon
Trout

15. Anthropogenic Problems
Two anthropogenic problems of freshwater systems are pollution and habitat destruction.
Pollution
Runoff from agricultural and urban
areas affects the water quality of
biomes.
Overuse and pollution threaten the
groundwater supply.

16. Habitat Destruction
People withdrawing water from freshwater
biomes cause them to shrink and degrade
plant and animal habitats.
Building dams and water diversion systems
block fish migration routes and destroy
irreplaceable plants and animals.

17. People can help preserve freshwater biomes by curtailing dam construction, reducing the use of pesticides and other water and plant pollutants and establishing protected wetlands areas.
