MODELING THE EFFECTS OF AN INTRODUCED SPECIES

Kit #547S — Developed by SEPUP

Students work in groups to use a set of cards to develop a food web model for one of four
ecosystems . Students are then given an additional card representing an introduced species .
They then consider the effects this new organism will have on the ecosystem and revise
their models to explain how the flow of energy and cycling of matter are disrupted by the
introduced species .
