Koalas are eating leaves on a sunny day. What is happening to the carbon in the air around the living things in the forest? Is carbon moving into the air, moving out of the air, or both?

• 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.

Saket has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has glass sides that allow sunlight to come in. The aquarium can also be covered to prevent light from entering.

The amount of carbon in the aquarium’s water started out high. Now, the amount of carbon in the water is decreasing.

Is the aquarium now in sunlight or is it covered? What is happening to the number of energy storage molecules in the plants and fish as a result?

• The aquarium is now in sunlight, and there are more energy storage molecules in the plants and fish.

• The aquarium is now in sunlight, and there are fewer energy storage molecules in the plants and fish.

• The aquarium is now covered so no light can get in, and there are more energy storage molecules in the plants and fish.

• The aquarium is now covered so no light can get in, and there are fewer energy storage molecules in the plants and fish.

This tortoise is eating cacti on a sunny day. 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 not moving into the air; it is only moving out of the air.

• Carbon is not moving anywhere

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

Scientists are studying cellular respiration in a jungle ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the jungle carry out cellular respiration?

• plants

• all organisms in the jungle

• animals and decomposers

• animals

A scientist set up an experimental ecosystem in a sealed room with no windows. The experimental ecosystem has plants and animals that eat those plants. The scientist can control whether the room is light or dark with a light switch outside the room.

The amount of carbon in the air of the ecosystem started out low. Then the amount of carbon in the air started to increase. Is the increase because the scientist switched the light on or because she switched the light off? What happened to the number of energy storage molecules in living things?

• switched the light off, and the number of energy storage molecules in the living things decreased.

• switched the light off, and the number of energy storage molecules in living things increased.

• switched the light on, and the number of energy storage molecules in living things increased.

• switched the light on, and the number of energy storage molecules in the living things decreased.

The amount of carbon in the bamboo and pandas . . .

• Stayed the same

• Decreased

• Increased

• There is no way to tell
