Students will use a food web to identify and distinguish producers, consumers, and decomposers, and explain the transfer of energy through trophic levels. Students will describe how relationships among organisms add to the complexity of biological communities.

You will use descriptions of organisms found in a freshwater marsh ecosystem and connect them according to their feeding relationships and the transfer of energy. Each of the biota cards represents a population. You will use this food web to explore the relationships among the organisms/populations in an ecosystem
