Matter and Energy in Ecosystems Review

A producer that lives in the water. It has been exposed to sunlight. What can the producers do because they are in sunlight? What does this mean for the number of energy storage molecules in the producer?

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

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

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

• give off carbon to the air allowiing the producer to use up energy storage molecules.

Does carbon moving into the water, moving out of the water, or both?

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

• Carbon is moving into the water and out of the water, at the same time

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

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

The amount of carbon in the air started out high in a closed ecosystem. But, over time the amount of carbon is decreasing. Do you think the model ecosystem now in sunlight or is it covered? What is happening to the number of energy storage molecules in the plants and animals as a result?

• The model ecosystem is in sunlight, and there are fewer energy storage molecules in the plants and animals.

• The model ecosystem is in sunlight, and there are more energy storage molecules in the plants and animals.

• The model ecosystem is covered so no light gets in, and there are fewer energy storage molecules in the plants and animals.

• The model ecosystem is covered so no light gets in, and there are more

It you have a clear glass tank with air, plants, and animals that eat those plants. The tank is closed so no material can get into or out of it, but light can get in when the tank is not covered. The light for the tank has been on all day, but the carbon in the air is decreasing. How is carbon moving between the air and the living things in the tank? What is happening to the amount of carbon in living things? Explain your thinking as completely as possible.
