How do lakes support biodiversity?
Lakes provide critical habitat for fish, crustaceans, molluscs, turtles, amphibians, birds, mammals, insects and aquatic plants, and support biodiversity on surrounding land. Due to the isolation between most lakes, many lakes harbor high numbers of endemic species, existing nowhere else on earth.
How does biodiversity affect water?

How does biodiversity protect water resources?
Biodiversity – Protection of water resources. Natural vegetation cover in water catchments helps to maintain hydrological cycles, regulating and stabilising water runoff, and acting as a buffer against extreme events such as flood and drought.
Why is it important to save lakes?
They provide water supply for the purpose of irrigation. Provide fresh water for drinking. … Proper lake functioning can ease the impact of floods and droughts in a particular area by storing large amounts of water in flood time and releasing it during shortages in drought.
Do lakes have a 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.
How does the water in ponds and lakes become impure?
Chemical Pollutants such as fertilizer and pesticides drain into ponds through run off and have negative impacts. Spills and leaks, run off from car washing, and even exhaust smoke from a running vehicle and all lead to the pollution of ponds.
Why is biodiversity important in streams?
Specifically, the study reveals how biodiversity helps remove excess levels of nutrients from streams that commonly degrade water quality. Cardinale said, “This is the first study that nails the mechanism by which biodiversity promotes water quality.
What is water biodiversity?

Aquatic biodiversity encompasses freshwater ecosystems, including lakes, ponds, reservoirs, rivers, streams, groundwater, and wetlands.
What are 5 benefits of biodiversity?
