  1. 01

    The Living World: Ecosystems

    • Use ecosystem structure, biomes, productivity, food webs, trophic levels, and biogeochemical cycles.
    • Explain energy flow and matter cycling.

    Practice: Analyze an energy pyramid and nutrient-cycle model with one quantitative calculation and one limitation.

  2. 02

    The Living World: Biodiversity

    • Explain biodiversity, ecosystem services, island biogeography, tolerance, disturbance, and succession.
    • Connect biodiversity to ecosystem resilience.

    Practice: Evaluate how a biodiversity change affects ecosystem services and long-term resilience.

  3. 03

    Populations

    • Use population growth, carrying capacity, survivorship curves, age structures, and human population dynamics.
    • Interpret demographic and growth data.

    Practice: Read an age-structure diagram and forecast one likely environmental pressure with evidence.

  4. 04

    Earth Systems and Resources

    • Use plate tectonics, soil, atmosphere, climate, global winds, and ocean-atmosphere patterns.
    • Connect geologic and atmospheric systems to resources and hazards.

    Practice: Explain a resource or hazard scenario using Earth-system evidence and uncertainty.
