✏️ Part 3: Short Answer Questions

I can: Explain human impacts on ocean systems and describe organism organization

7. Explain what happens to energy as it moves up the food chain. Why is less energy available at higher trophic levels?

8. Describe two ways that plastic pollution affects ocean organisms and food webs.

9. How does overfishing of large predators like sharks affect the entire ocean ecosystem? Give a specific example.

10. Compare and contrast the organization levels: population, community, and ecosystem. Use ocean examples.

Extension Activity: Research a specific ocean dead zone and create a diagram showing how human activities led to its formation. Include at least 3 trophic levels affected.

Success Criteria: I can identify trophic levels (4-5 correct), explain energy transfer (clear explanation), describe human impacts (2+ specific examples), and organize ocean life into populations, communities, and ecosystems.
