Redwood trees in northern California grow to great heights. The sun has been up for several hours, and it has been shining on these trees. What has the sunlight caused the trees to do? What has happened to the number of molecules that store energy in the trees? Sunlight has caused the trees to . . .

• give off carbon to the air. The number of molecules that store energy in the trees has increased.

• give off carbon to the air. The number of molecules that store energy in the trees has decreased.

• take in carbon from the air. The number of molecules that store energy in the trees has increased.

• take in carbon from the air. The number of molecules that store energy in the trees has decreased.

Some goats live on the sides of steep mountains and eat the grass and bushes that grow there. It's a clear, sunny day on the mountainside. 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.

An aquarium is filled with water and contains plants and fish that eat the plants. It is sealed so no material can get in or out, but the glass sides allow light to come in when the aquarium is not covered.The amount of carbon in the water started out high. During a certain period of time, the amount of carbon in the water decreased. Was the aquarium in sunlight or was it covered during this period of time, and what happened to the number of molecules that store energy in the plants and fish?

• The aquarium was in sunlight, and there are more molecules that store energy in the plants and fish.

• The aquarium was in sunlight, and there are fewer molecules that store energy in the plants and fish.

• The aquarium was covered so no light got in, and there are more molecules that store energy in the plants and fish

• The aquarium was covered so no light got in, and there are fewer molecules that store energy in the plants and fish

A herd of deer lives in the forest where they eat the leaves of trees. The number of molecules that store energy in the trees and in the deer has increased. What has happened to the amount of carbon in the trees and in the deer? The amount of carbon in the trees and in the deer . . .

Responses

• has increased

• has decreased

• has not changed

• is not related to the number of molecules that store energy.
