NGSS Standards
- HS-LS2-3 — Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions. (Energy flow)
- HS-LS2-6 — Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but shifting conditions may result in a new ecosystem. (Stability & change)
- HS-LS2-8 — Evaluate evidence for the role of group behavior on individual and species chances to survive and reproduce. (Evaluating solutions)
