Fresh Water
- very low salt concentration, less than 1%
- ponds, rivers, wetlands, lakes, streams
- these areas support many aquatic species
- only 3% of water on Earth is fresh water
- less than 1%is available for human use
- fresh water has a density of 1,000 kg/m3
- animals that live in this environment are
Brackish Water

- May be dangerous to the environment
- More salinity than fresh water
