Students apply ecosystem knowledge to adaptations and food chain reasoning. Part A has four multiple-choice questions about arctic fox camouflage, correct food chain order, and classifying a bear as an omnivore consumer. Part B has five fill-in-the-blank problems about an organism's niche, camel eyelashes, and the role of tadpoles in a pond ecosystem.
These problems challenge third graders to explain why adaptations exist rather than simply name them.
