This series uses cartoon-style illustrations and humorous narrative text to make key topics in Science and Geography accessible and engaging. This approach encourages children to read about and understand complex ideas. The story looks at a food chain on the grasslands of Africa. We find out how plants create their food from sunlight. We see the way insects feed on plants and birds feed on insects. How zebras feed on grass, and lions feed on zebras. Each creature has its own source of food - and forms part of the food chain. The book also contains an experiment, useful websites and an index.
