Transcript of Freshwater Wetlands

The freshwater wetland biome is a hybrid between water and land. Swamps, marshes, and flood plains are all examples of a freshwater wetland. Many of these wetlands can be found near rivers, or other natural abundances of water.

Major Herbivores Freshwater wetlands are very good habitats for herbivores. Freshwater wetland herbivores include moose, beavers, muskrats, and duck. Without the thousands of species of producers in wetlands, these organisms would not be able to survive. Carnivores Wetlands play a critical role in regulating the movement of water within watersheds as well as in the global water cycle Wetland carnivores include: Great Blue Heron, trout, Bullfrog, Snapping Turtle, Marsh Hawk (Northern Harrier), and weasel. These animals only get one percent of the energy that the producers originally had. Omnivores Omnivores found in a wetland would include a Painted Turtle, Red Fox, Raccoon, and Striped Skunk. Snapping Turtles, snails, and crayfish Omnivores found in a wetland include Painted Turtles, Red Fox, Raccoons, Striped Skunks, Snapping Turtles, snails, and crayfish. Most of these animals prey off of a majority of plants excluding the red fox. Detrivores The most common decomposers in freshwater wetlands are bacteria and fungi. Detrivores are very important to an ecosystem. Without them, nutrients could not be recycled. Above these energy levels should also be detrivores. 100% 10% 1% .1% 90% percent of energy is given off as heat at each level Biogeochemical Cycles The nitrogen cycling process in wetlands involves both aerobic and anaerobic conditions. Some think of wetlands to be "kidneys" for the nitrogen cycle, due to the trapping of pollutants in layers of soil floating on the water. Wetlands contain an abundance of algae in their water. This algae can help reduce the amount of carbon in the carbon cycle by absorbing CO2 and releasing it as oxgen and energy. There are many ways in which humans impact freshwater wetlands. As humans, we use wetlands to dispose of copious amounts of the waste we create. Humans are using wetlands for things such as: Mining, run-off, release of toxic chemicals, grazing of domestic animals. There is also invasion of alien species. It is estimated by the EPA that on nonfederal lands alone, anywhere from 70 to 90 thousand acres of wetlands are lost each year to progress and development. Due to this pollution, many of the weaker species in freshwater wetlands are in danger of dying off. This means the biodiversity of wetlands will decrease due to survival of the fittest. How can we fix this? I think the best way to fix this is to offer money for safely disposing of these waste products. In doing this, we could use the money that we would originally pay on wetland restoration to bribe the main polluters. Did you know? The area of the globe covered by wetlands is constantly shrinking and has decreased by 6% in the last two decades. The main reason why wetlands are shrinking is the human population growth. Also, According to the UN Millennium Ecosystem Assessment, environmental degradation is more prominent within wetland systems than with any other ecosystem on Earth. Works Cited
