Talking about the desert always brings to mind sand, heat, and barren landscapes. However, the desert can also be very cold at night and can support certain forms of plant life. The plants help the animals of the desert to survive by being part of the food chain. Animals of the desert provide meat and milk for the people of the desert, thus being a part of the food chain. Because a creature such as a lizard might eat seeds or small insects in dry weather and plants during wet weather, the amount of rainfall in the desert can be critical to the food chain. Many desert dwellers are introduced in these pages, with each two-page spread showing the food chain for that particular creature. For example, the roadrunner bird eats lizards that eat tadpoles. Tadpoles eat water fleas that have feasted on algae. The photographs are excellent and the glossary and index help direct young researchers. An explanation of food webs is included in the help pages. Several web sites are suggested for further study. This is a part of the series "Food Chains in Action." Other titles in this series discuss city habitats, the seashore, the grasslands, rivers and lakes, and the rain forest.
