An ecosystem is an enormous network made up of many different organisms, all of which rely upon one another to make sure the system works. Four titles have been added to Ecosystems Inside Out, a fascinating series that explores the big picture of each amazing biome on Earth, then peels back its corners to reveal the fascinating details of the organisms that live there. Each spread focuses on one particular organism within that ecosystem, explaining how it lives and functions within the system, and the crucial role it plays within it. Easy-to-follow text discusses how our planet relies upon this network of ecosystems for life to flourish, and gives readers ideas on what they can do to help protect them. Eco Focus boxes, locator maps, and an activity in each book help give young readers a close-up look at how living and nonliving things are interconnected in ecosystems.
