The main source of energy for photosynthesis comes from...
6CO2 + 6H20 + light energy -> C6H12O6 + 6O2
In this chemical equation, the highlight red things are called the ______.
CO2 (Carbon dioxide) + light + H2O --> O2 + glucose
O2 (oxygen) + light + H2O --> CO2 + glucose
A student is collecting the gas given off from a plant in bright sunlight where it is 90 degrees. The gas being collected by the student is ______________.
If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s photosynthesis?
Photosynthesis won't happen because there is no carbon dioxide to be absorbed.
There will be MORE photosynthesis
Two of the reactants of photosynthesis are
sugar and water.
sugar and oxygen.
carbon dioxide and water.
carbon dioxide and oxygen.
Which gas is taken in by producers (plants) during Photosynthesis?
oxygen

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?
The trees can . . .
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.
Place the organisms in the correct category.
Sunflower
Cougar
Mouse
Raccoon
Snake
