  • Question 9
    30 seconds
    Q.

    The carrots, grasses, and grains are producers in this food web. Why are they called producers?

    answer choices

    They have the ability to produce carbon.

    They have the ability to produce glucose.

    They have the ability to produce light energy.

    They have the ability to produce water.

  • Question 10
    30 seconds
    Q.

    How does the oxygen produced by the plant during photosynthesis escape into the air?

    answer choices

    through large holes in the stem

    released when an animal eats a plant

    through the roots

    through tiny openings called stomata
