Lisa has a glass ball filled with water. In the water are tiny plants and shrimp that eat the plants. No material can get in or out, but sunlight can get through the glass. The glass ball can also be covered to prevent light from entering. The number of energy storage molecules in the plants and shrimp started out low but now it is increasing. Is the glass ball in sunlight or is it covered? What is happening to the carbon in the water inside the glass ball?

• The glass ball is covered so no light gets in, and there is more carbon in the water now than there was before.

• The glass ball is covered so no light gets in, and there is less carbon in the water now than there was before.

• The glass ball is in sunlight, and there is less carbon in the water now than there was before.

• The glass ball is in sunlight, and there is more carbon in the water now than there was before.

Mark has an aquarium filled with water, plants, and fish that eat those plants. It is sealed so no material can get in or out, but the glass sides allow light to get in. The aquarium can also be covered to prevent light from entering. The amount of carbon in the water started out low. Now, the amount of carbon in the water is increasing. Is the aquarium now in light or is it covered? What is happening to the number of energy storage molecules in the living things?

• The aquarium is covered (so it's dark), and there are more energy storage molecules in the living things.

•  The aquarium is covered (so it's dark), and there are fewer energy storage molecules in the living things.

• The aquarium is uncovered (so it's light), and there are more energy storage molecules in the living things.

• The aquarium is uncovered (so it's light), and there are fewer energy storage molecules in the living things.
