The process of photosynthesis is essential in the carbon cycle. Photosynthesis removes carbon dioxide from the atmosphere and produces/releases oxygen back into the atmosphere.
2. A student is completing an experiment comparing plants in two areas. Both areas have the same type of plants with equal sunlight and equal available water. Area 1 has a high amount of carbon dioxide in the atmosphere, and area 2 has a low amount of carbon dioxide in the atmosphere.
How does the rate of photosynthesis in area 1 compare to the rate of photosynthesis in area 2?
(1 point)
Responses
The rate of photosynthesis increases with a decrease in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with a decrease in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis decreases with an increase in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis decreases with an increase in carbon dioxide; therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
The amount of carbon dioxide in the atmosphere has no affect on the rate of photosynthesis; therefore, area 1 and area 2 will have the same rate of photosynthesis.
The rate of photosynthesis increases with an increase in carbon dioxide; therefore, area 1 will have a higher rate of photosynthesis compared to area 2.

To correctly complete the sentence, we need to select the appropriate terms from the drop-down boxes. Let's analyze the sentence and the options in each drop-down box.
The first drop-down box options:
- Oxygen
- Carbon dioxide
- Water
Based on the context of photosynthesis and the carbon cycle, we know that photosynthesis removes something from the atmosphere. During photosynthesis, plants take in carbon dioxide from the atmosphere, and through the process, something is produced or released. Therefore, we should select "Carbon dioxide" from the first drop-down box.
The second drop-down box options:
- Oxygen
- Carbon dioxide
- Water
Considering that photosynthesis produces or releases something back into the atmosphere, we know that plants release oxygen during this process. Therefore, we should select "Oxygen" from the second drop-down box.
So, when we combine the selections from each drop-down box, the completed sentence is:
"The process of photosynthesis is essential in the carbon cycle. Photosynthesis removes carbon dioxide from the atmosphere and produces/releases oxygen back into the atmosphere."
By understanding the concepts of photosynthesis, the carbon cycle, and the functions of different substances in these processes, we can correctly complete the sentence.
