All plants and animals are links in food chains. The 11 pages in this lesson look at what energy is and how this energy is transferred from one organism to the next. Food webs and the concept of a food pyramid are also explained. A step-by-step animation shows what the Balance of Nature is and how this can be affected by external influences. Whiteboard activities give students the opportunity to group animals into feeding categories and create a marine and a garden food chain. A follow-up printable worksheet is also available.
