Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and what type of consumer; herbivore, omnivore, or carnivore. Students will be provided with a list of Sonoran Desert species and asked to construct, within their groups, several food chains. These food chains will then be used to construct a food web. In order to complete this activity, students must first research the individual species to understand their feeding habits.
