HS-LS2 Ecosystems: Interactions, Energy, and Dynamics

• HS-LS2-1
  Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
• HS-LS2-2
  Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
• 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.
• HS-LS2-4
  Use a mathematical representation to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
• HS-LS2-5
  Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
• 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 changing conditions may result in a new ecosystem.
• HS-LS2-7
  Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
• HS-LS2-8
  Evaluate the evidence for the role of group behavior on individual and species' chances to survive and reproduce.
