Publisher's Synopsis
It might be difficult to imagine what would happen on Earth if prairie dogs, mountain lions, or sea urchins disappeared. With content centering on keystone species, food webs, and ecosystems, these books investigate that very notion through content directly relating to the science curriculum. Each book considers a different animal's impact on its environment and how all the parts of an ecosystem work together. Assisted by colorful close-up photographs of the animals and their home, the main content engages young, curious readers with the world around them in a new way. Features include: Presents concepts of conservation. Correlates with the Next Generation Science Standards for 2nd grade, which includes understanding "interdependent relationships in ecosystems." Encourages critical thinking through the answers to the title's question.
