How do plants reproduce? What are the life stages of a caterpillar? Where do turtles lay their eggs? Life Cycles introduces how the lives of plants and animals can be very different, from 2,000 year old sequoia trees to 70-year-old elephants to adult mayflies that only live a few hours. Readers will look at similarities between living things, such as how comparing a cuckoo and a cheetah illustrates how many animal parts are similar. Readers will also gain a basic understanding of animal and plant life cycles as they read about examples from all over the world.
