Freshwater animals are the invertebrate and vertebrate species live in freshwater ecosystems such as lakes, ponds, rivers, etc. Via excretory processes, animals can supply nutrients (nitrogen and phosphorus) at rates comparable to major nutrient sources, and nutrient cycling by animals can support a substantial proportion of the nutrient demands of primary producers. An extraordinary number of different fish species can also been found in rivers and streams all over the world. And they are stressing plants and animals in freshwater ecosystems, in some cases until they disappear. Beaver The beaver is a large rodent that builds dams and dens.
