    • algae
    • prairie grass

  2. Which energy path fits the forest food web?

    • woodpecker -> caterpillar -> oak tree -> Sun
    • caterpillar -> oak tree -> woodpecker
    • mushrooms -> Sun -> woodpecker
    • Sun -> oak tree -> caterpillar -> woodpecker

  3. What role do decomposers such as soil bacteria have in the prairie ecosystem?

    • breaks down dead matter and returns materials to the system
    • turn consumers into rocks
    • hunt all predators
    • make sunlight for producers

  4. If caterpillars decrease in the forest, what is a likely effect?

    • sea otters may have less food if sea urchins decrease
    • lady beetles may decrease if aphids decrease
    • hawks may have less food if rabbits decrease
    • woodpeckers may lose a food source if caterpillars decrease
