Extension:
The source of energy that drives most of Earth’s ecosystems is radiant energy from the
Sun. Describe radiant energy.
What property does radiant energy have that allows the Sun to get energy all the way to
Earth?
How could you prove the hypothesis that plants must have light? Describe your
experiment below. You can add a drawing if it will help explain your experiment.
