Big Ideas
- Ecosystems are dynamic systems where the flow of matter and energy and the interactions between organisms determine stability, diversity, and change.
- Human activities, environmental changes, and group behaviors impact ecosystem carrying capacity, biodiversity, and survival of species.
Essential Questions
- How do factors like resources and environmental conditions affect the carrying capacity of ecosystems at different scales?
- In what ways do matter and energy cycle within ecosystems, and how do aerobic and anaerobic conditions influence these processes?
- How do photosynthesis and cellular respiration drive the cycling of carbon among Earth’s systems?
- What evidence supports the role of group behavior in the survival and reproduction of species?
- How can we design or refine solutions to reduce the impacts of human activities on ecosystem health and biodiversity?
