Using examples of food chains and food webs, describing the difference between producers and consumers, and illustrating the importance of scavengers and decomposers in maintaining a healthy ecosystem, this program explores the dynamic relationship between plants and animals in a shared ecosystem. The presenter-led, nature documentary-style video is also ideal for sparking classroom discussion on environmental issues such as climate change, deforestation, and species extinction.
