Students fix habitat errors and learn the term ecosystem. Part A corrects three sentences placing a monkey in the tundra, sea turtles on the ocean floor, and a cactus in a rain forest. Part B has four fill-in-the-blank problems about ecosystems, tundra traits, and ocean animals. Part C has three true-or-false statements about what ecosystems include, habitat flexibility, and cactus adaptation.

Introducing ecosystem alongside habitat helps students begin to see the broader living-and-nonliving picture.
