Open direct link

Evidence of understanding

  • Draws a food web from given data with arrows showing energy flow direction
  • Predicts how the population of one species would change if another species increased or decreased
  • Distinguishes a food web from a food chain and explains why webs are more realistic
  • Identifies producers, primary consumers, secondary consumers, and apex predators

Assessment prompt

If Food Webs & Interdependence was shown a diagram with lots of animals connected by arrows, could they explain what it means — tracing what eats what — and predict what would happen if one animal disappeared from the web?
