Ages 5 to 9 years. Plants and animals in the Sonoran Desert food chains have had to adapt to the hot, dry climate of this habitat. Conserving water is a large part of these food-chain adaptations. Learn about the spectacular Saguaro cacti and the many herbivores and carnivores that are part of the food chains of this desert. Children will learn about: how plants make food; how desert plants and animals adapt to drought and heat; desert hunters and scavengers; dangers to Sonoran Desert food chains and webs; how to help save desert plants and animals.
