Summarize how the internal stimuli (including hunger, thirst, and sleep) of animals ensure their survival.

Illustrate energy flow in food chains, food webs, and energy pyramids

Explain the interaction among changes in the environment due to natural hazards (including landslides, wildfires, and floods), changes in populations, and limiting factors (including climate and the availability of food and water, space, and shelter).

Summarize how the location and movement of water on Earth’s surface through groundwater zones and surface-water drainage basins, called watersheds, are important to ecosystems and to human activities.
