商品簡介
Who's keeping the ecosystem healthy?
In any ecosystem, every species has a role to play. From towering trees and ginormous whales to the smallest microorganisms, plants, fungi, and insects, each species is important to the overall health of the ecosystem. But some of those species play such vital roles that without them, the ecosystem might collapse. These are called keystone species.
In Keystone Species: Meet the Animals Key to Ecosystem Health and Biodiversity with Hands-On Science Activities for Kids, readers ages 9 to 12 are introduced to several different types of keystone species from around the world as they discover the crucial roles these animals play in their ecosystems. Meet the predators, herbivores, ecosystem engineers, mutualists, and foundational species that all play a keystone role in regulating an ecosystem. Investigate how these ecosystems function, learn about threats to wolves, sharks, beavers, alligators, flying foxes, bees, wildebeests, bison, and coral, and dive into what happens when these species disappear. Throughout the book, find stories about science-based conservation practices that inspire kids to do their part in protecting their own environments.
Keystone Species includes hands-on activities and critical thinking exercises to help readers gain a deeper understanding of ecosystems and the role of every species. STEM activities, a narrative writing style, fun facts, words-to-know, and links to primary sources, videos, and other relevant websites take readers on an exploration of keystone species around the world.
Additional materials include a glossary, a list of media for further learning, a selected bibliography, and index. All books are leveled for Guided Reading level and Lexile and align with Common Core State Standards and Next Generation Science Standards.
All titles are available in paperback, hardcover, and ebook formats.
