Focus on Food Webs

Food webs map out who eats whom in an ecosystem. Using a freshwater ecosystem as an example, we will assign each student to an organism and build an intricate food web out of yarn. Which ones are the producers, consumers, and decomposers? How about the herbivores, carnivores, and omnivores? We’ll also touch on how energy from the sun is transferred to plants and then to animals in the food web. We’ll see how disturbance impacts the interconnectedness of the food web. Lastly, students will get to meet a couple charismatic live members of the freshwater ecosystem. In-person only. This program corresponds well with the Pond Prowl program.
