Swamps and Such. This video series from WOSU Public Media uses the example of a wetland to explain the structure and functions of ecosystems and how ecosystems change over time. In these videos meet wetland scientist Dan Fink who hosts the program and examines the types of communities of plants, animals, birds and fish that abound in wetlands, the process of photosynthesis, and the complex relationship between water and productivity. Developed in collaboration with The Ohio State University Olentangy River Wetlands and Research Park in Columbus, Ohio, this program was videotaped entirely at the Olentangy River Wetlands.

Print Background EssayNature’s Supermarket. Wetlands are highly productive ecosystems. As a measure, consider that most forests produce two grams of carbon per square meter per day. A wetland produces twice as much—four grams of carbon per square meter per day. The forest is akin to a supermarket with empty shelves. In contrast, a wetland would appear to be a well stocked supermarket.
It takes a lot of energy to sustain this production. The energy mostly comes from the sun via photosynthesis. The energy is transferred from the sun to plants then to animals in a complex food chain. Only about 10% of the energy stored and used by one animal is gained by a predator specie. A healthy wetland is a veritable buffet of food choices for the different animals.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.Source: Swamps and Such
