Big Ideas
- Ecosystems depend on the availability of resources and interactions among organisms to maintain balance.
- Both physical and biological changes, as well as human-designed solutions, impact ecosystem health and biodiversity.
Essential Questions
- How does resource availability influence the populations of organisms in an ecosystem?
- What patterns exist in the ways organisms interact within and across different ecosystems?
- How do matter and energy cycle through the living and nonliving parts of an ecosystem?
- In what ways can changes to physical or biological components affect population dynamics?
- How can competing solutions be evaluated to best maintain biodiversity and ecosystem services?
