Ecosystems: Interactions, Energy, and DynamicsHS-LS2

  • HS-LS2-1.

    Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.HS-LS2-1

  • 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-LS2-2

  • 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-LS2-3

  • 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-LS2-4

  • 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-LS2-5

  • 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-LS2-6
