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 sunlight? What does this mean for the number of energy storage molecules in the trees?
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.
Will 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.

Amount of Carbon stays the same
New Carbon is created when old carbon decomposes
True or False: Earth is a closed ecosystem.
True
False
Since almost no carbon enters or leaves Earth’s system, and carbon isn’t being produced or used up, the amount of carbon in the system does
