In Ecology: Interactions in the Biosphere students will learn about the biotic factors (living things) and the abiotic factors (nonliving things) that interact to affect life on Earth. Students will explore the various habitats on Earth and the niches that organisms fill within those habitats. They will learn about the relationships among organisms in food chains and food webs, cycles of resources, and various types of pollution. Students will examine how these factors contribute to climate change. Research projects will encourage students to learn science concepts while helping to make a difference in their own communities. This book is designed to supplement your existing science curriculum. The pages may be reproduced for your use in the classroom or home school. Features include: - Water Cycle, Oxygen-Carbon Dioxide Cycle, and Nitrogen Cycle illustrations - Vocabulary study guide - Unit test for assessing mastery of ecology material - Research activities and ecology projects
