POINTS TO THINK ABOUT
  • Frogs are not the only animals to eat insects. Wherever this 'crossover' occurs is when a food chain becomes a food web.
  • What do you think would happen to the food chain if one year a lot of the frog spawn did not hatch into small frogs because of drought or poisoning for instance?
  • What do you think would happen if many of the eagle nests were damaged by egg poachers or high winds?
POINTS TO THINK ABOUT
  • Jellyfish are not the only animals to eat krill. Wherever this 'crossover' occurs is when a food chain becomes a food web.
  • What do you think would happen to the food chain if one year a lot of the krill disappeared due to the water temperature rising and killing them off?
  • What do you think would happen if many of the turtle eggs one year were eaten by predators?

  • What do you think would happen to the food chain if one year a lot of the sea urchins disappeared due to the water temperature rising and killing them off?

  • What do you think would happen if humans over fished the lobster population?
