How does wetlands purify water?
Wetlands as Water Treatment
As sediment, excess nutrients and chemicals flow off of the land, wetlands filter the run off before it reaches open water. Nutrients are stored and absorbed by plants or microorganisms. … This natural purification definition is an example of the value of wetlands in our environments.
What are the benefits of wetlands?

Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain.
Which of the following is one reason that wetlands are important?
Wetlands are highly productive and biologically diverse systems that enhance water quality, control erosion, maintain stream flows, sequester carbon, and provide a home to at least one third of all threatened and endangered species. Wetlands are important because they: improve water quality. provide wildlife habitat.
