Is biodiversity in freshwater high?
freshwater includes rivers, lakes and wetlands and are habitats which are rich in biodiversity. such systems provide us with many services such as our drinking water, food (such as fish), a means of transport as well as recreational opportunities.
How much biodiversity is in freshwater?
Fresh water makes up only 0.01% of the World’s water and approximately 0.8% of the Earth’s surface, yet this tiny fraction of global water supports at least 100000 species out of approximately 1.8 million – almost 6% of all described species.
Is River biodiversity high?
River systems are the zone of Earth’s highest biological diversity – and also of our most intense human activity. … They reduce water and sediment flows to downstream habitat, and change the nature of a river’s estuary, where many of the world’s fish species spawn.
How does biodiversity affect freshwater?
New study shows how greater biodiversity more efficiently scrubs pollutants from freshwater. A new landmark study not only proves that adding more species to a freshwater stream linearly increases the ecosystem’s ability to clean pollutants, but also shows why.
Do lakes have high biodiversity?
Ecosystems that are based upon freshwater, such as lakes and rivers, also have high biodiversity. Habitats that are both marine and freshwater (estuaries and salt marshes) are some of the harshest areas on the planet to live. Therefore, the biodiversity in these areas is quite low.

Is low biodiversity?
Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
