Earth's Ecosystems and Habitats

The video tutorial reviews the Earth's four spheres and introduces habitats, ecosystems, and biomes. It explains the needs of living organisms for survival and compares human and animal habitats, focusing on beavers. The tutorial includes an activity for students to draw their homes and observe live nature streams. It concludes with a discussion on how communities resemble ecosystems and an Earth stewardship pledge.

What is the purpose of the Earth Stewardship Pledge?

• To commit to caring for the environment

• To learn about different animal species
