What Makes Living Things Go?

What Makes Living Things Go? follows the energy source for one animal to show students that energy is used for many things such as movement, growth, and reproduction. The book explores the ways in which organisms are classified in particular roles (producer, consumer, herbivore, carnivore, omnivore, decomposer) based on how they take in and use energy, but points out that not every instance is straightfoward. Emphasis is placed on understanding that all energy can eventually be traced back to the Sun.
