This activity gives students producers, herbivores, carnivores (and in one ecosystem, omnivores) and asks them to construct an appropriate food web. Students may find pictures of the organisms on the internet and use those to construct their food webs. There are 3 different ecosystems provided: deciduous forest, jungle, and fresh water habitats. This activity is easily differentiated, as the deciduous forest habitat is slightly more difficult, to challenge accelerated students. You could have students swap food webs and do peer review as well.
Full answer key is provided.
