Help your students build real understanding of human impacts on biodiversity through ninety questions that move from basic recognition to genuine reasoning about living systems.

The set includes questions like "Which of the following human activities can restore biodiversity?", "Which of the following is a long-term effect of pollution on ecosystems?", and "What is a common result of habitat fragmentation?"

What's Inside?

• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
