Las cadenas alimentarias en el bosque (Forest Food Chains) [PDF ebook] 

A forest is an ecosystem with a variety of plant and animal life—from trees to deer. These plants and animals are connected through food chains, or the passing of energy from one living thing to another. In this volume, readers explore a forest for themselves, learning about the living things that can be found there. Informative text and fun fact boxes explain the connections between forest creatures, and vibrant photographs of forest wildlife fill each page. Readers can even visualize the way food chains come together as they study a detailed forest food web.
