Human Impact on Ecosystems and Strategies

This video is a study session for AP Biology's ecology unit, covering key topics and strategies. It includes creating a concept map to connect ideas, using charts to organize information on environmental disruptions, and practicing with questions to reinforce learning. The video emphasizes the importance of making connections between concepts and provides examples of disruptions like invasive species and human impact. It concludes with a review of practice questions to assess understanding of topics such as the carbon cycle and predator-prey relationships.
