树是一种非常有价值的自然资源。人类从树上采集果实,动物在树上安家、觅食。最重要的是,我们离不开树,因为树能提供给我们所需要的氧气。树给予我们许多丰富多彩的产品。我们必须保护树,没有它们,我们就无法生存。

Food Chains and Food Webs
Informative and intriguing, this science book teaches children to think about the complex and interdependent web of life on Earth. Every link in a food chain is important because each living thing depends on others for survival, no matter how big or how small. Lively drawings from Holly Keller illustrate the clear, simple text by Patricia Lauber. This is a Stage 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts for children in the primary grades. Let's-Read-And-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series. Supports the Common Core Learning Standards and Next Generation Science Standards
