A simple food chain in a broadleaf forest is described. The giant panda is discussed as an example of an animal that relies on a single food source. It has now become endangered due to humans destroying its food source. A coastal food chain is used to exemplify how population changes are interconnected through food webs, but in theory are self-balancing.
The clip shows students how food chains can be combined to form food webs and also shows how different species are interconnected through feeding relationships. Can students think of other examples of food webs?
