The moment you step out the front door you are walking into a biome, and your own backyard is part of an ecosystem. The climate, animals, and vegetation vary in many different parts of the world, which make each area a specific biome with its very own characteristics. When the seasons change, the weather changes and the environment changes, too—and one little change in the ecosystem can effect the whole biome. By viewing this video, students will learn about several different major biomes of the world and how they interact with each other. After viewing Ecosystems and Biomes, students will be able to define ecosystems and biomes, appropriately use introduced vocabulary in writing and discussion, identify the seven major biomes, list characteristics of different biomes, identify the geographic locations of the major world biomes, and be more aware of the role of the environment and its job in the ecosystem.
