In the animal kingdom, cause and effect can sometimes be a matter of life and death! But chaos also plays a role in cause and effect, because sometimes unexpected events change the usual outcomes. Throughout this volume, readers learn about different situations in the animal kingdom that lead to another situation, as well as the chaos that can occur at the hands of human involvement--like overfishing or poaching. Colorful illustrations demonstrate the various processes for readers, as they learn to connect cause-and-effect outcomes with the help of arrow diagrams.
