Ecosystems Carbon Flow

Student Directions

Imagine a dead cow lying in a field of grass in the midwest somewhere. The two graphs below show the percent distribution of the cow's carbon in different parts of the grass ecosystem after one month and after one year. Draw two box-and-arrow diagrams (one for each graph) showing and explaining what happens to the carbon in the cow based on the data in the graphs (that is, where the C goes). In addition to the different components of the ecosystem (e.g. cow, air, microbes etc.) show and briefly explain the different processes? involved.
