Wetland functions and ecosystem benefits. Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Because wetlands are often transition zones (ecotones) between terrestrial and deepwater aquatic systems, many processes have major implications for species. Since wetlands may provide food and habitat for many terrestrial and many aquatic species, wetland biodiversity is often higher than that of adjacent ecosystems.
Wetlands are not considered freshwater ecosystems as there are some, such as salt marshes, that have high salt concentrationsthese support different species of animals, such as shrimp, shellfish, and various grasses. Visit our gallery of wetlands images, which illustrate the amazing diversity of wetland ecosystems.lants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There are different types of freshwater regions: ponds and lakes, streams and rivers, and wetlands.
