The sun has been up for several hours, and it has been shining on these trees. What can the trees do because they are in the sunlight? What does this mean for the number of energy storage molecules in the trees?The trees can . . .

• give off carbon to the air. Giving off carbon allows them to make energy storage molecules.

• give off carbon to the air. Giving off carbon uses up energy storage molecules.

• take in carbon from the air. The carbon is used to make energy storage molecules.

• take in carbon from the air. The carbon is used to break down energy storage molecules.

These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain? Is carbon moving into the air, moving out of the air, or both?

• Carbon is only moving into the air; it is not moving out of the air.

• Carbon is moving into the air and out of the air at the same time.

• Carbon is not moving into the air; it is only moving out of the air.

• With this information, there is no way to know for sure.
