What is Freshwater Biome ?
Freshwater biome is made up of any of body of water that is made of freshwater such as lakes, ponds, streams, and rivers. They cover about 20% of the Earth and is spread out all over the world. Most freshwater biomes consist of moving water and contain many types of fish.
Saltwater vs. Freshwater
The main difference between salt water andfresh water is the salinity content. Both contain salt or sodium chloride, but fresh water contains only small amounts of salt. The earth's oceans and seas are saltwaterecosystems, while lakes, rivers, streams, marshes and ponds are freshwaterecosystems.
Freshwater Biomes
Geography
- Freshwater biomes are lakes, ponds, rivers and streams
- Moving bodies of water are called rivers and streams. They mostly come from mountains, ground water and melting ice.
- Ponds are small bodies of water surrounded by land. Lakes are bigger that ponds, which is also surrounded by land.
Vegetation
- Vegetation is important to freshwater biomes because it provides oxygen.
- Vegetation also provides food for the animals in the biome.
- Vegetation help some plants have strong roots.
- Most of the plants are able to cling to rocks.
- Other plants that live in still waters normally float on the surface.
Animals
- Animals that live in fast moving water have adaptations that help them survive. Example is suction cups that allow them to hold on to rocks.
- Some animals such as fish, birds, insects and amphibians live in still water environment.
- A lot of freshwater animals live in Estuaries.

Human influences
The human impacts of freshwater biomes are immense for example if global warming continues lake Michigan will continue to lose water and as a result the heat of lake Michigan increase and the circulation of oxygen will slow which will kill off everything in the lake. This also increase the amount of pollution in the water.
