Transcript of Freshwater biome
Freshwater is a body of water with a low salt concentration.
Aquatic - Freshwater Biome
Regan Allen, Daniel Tate, Doug Blythe
The different types of freshwater regions are: ponds, lakes, streams, rivers, and wetlands. Many abiotic and biotic organisms can be found in this biome.
Biotic and Abiotic
Factors to endangered , extirpated , threatened & at risk species
Humans destroy species homes from industries that contaminate the water.
-Dumping of sewage and industrial waste (oil spills)
-Loss of habitat
-Inbalance of PH
- Invasive species
-Pollution/ air and water quality
-Producers & consumers
-Variety of fish
-Variety of plants
-Create more habitats
-Keep out invasive species
-Not enough light or temperature / climate change
Freshwater ecosystems are essential for human survival, providing the majority of people's drinking water. The ecosystems are home to more than 40 percent of the world's fish species. Despite their value and importance, many lakes, rivers, and wetlands around the world are being severely damaged by human activities and are declining at a much faster rate than terrestrial ecosystems.
More than 20 percent of the 10,000 known freshwater fish species have become extinct or imperiled in recent decades. Watersheds, which catch precipitation and channel it to streams and lakes, are highly vulnerable to pollution. Programs to protect freshwater habitats include planning, stewardship, education, and regulation.
Freshwater in the form of rivers, lakes, groundwater and wetlands offers us a remarkably diverse array of natural functions and ecosystem services. However, there is clear and growing scientific evidence that we are on the verge of a major freshwater biodiversity crisis: in the 30 years between 1970 and 2000, populations of more than 300 freshwater species have declined by 55% while those of terrestrial and marine systems each declined by 32%
