Summary:
In this activity, students will use data from natural parks to examine terrestrial trophic cascades. Concepts will then be applied to examples in freshwater ecosystems.

Description
This resource is a case study learning activity to accompany the HHMI Video Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades.
Notes
Despite the focus on terrestrial trophic cascades, the material was easy to apply to the water ecology course I utilized it in. Students were then asked to apply the concepts to algae we were learning to identify and their predators in freshwater systems.
