In order to increase the amount of oxygen produced by a plant, available

Rationale

Increasing the available carbon dioxide will increase the amount of oxygen produced by a plant.

Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose. This process requires carbon dioxide and water, and it produces oxygen as a byproduct. Therefore, increasing the amount of available carbon dioxide will allow for more photosynthesis to occur, increasing the production of oxygen.

A (glucose should be increased) YOUR ANSWER

Glucose is a product of the photosynthesis process, not a reactant. Increasing the glucose level will not promote photosynthesis or increase the production of oxygen.

B (carbon dioxide should be increased) CORRECT

Carbon dioxide is a key reactant in the photosynthesis process. By increasing the carbon dioxide level, plants can perform more photosynthesis, which in turn increases the production of oxygen as a byproduct.

C (carbon dioxide should be decreased) YOUR ANSWER

Decreasing the carbon dioxide level would limit the amount of photosynthesis that can occur, which would consequently reduce the production of oxygen. This is the opposite of the desired effect.

D (glucose should be decreased) YOUR ANSWER

Decreasing the level of glucose will not have a direct influence on the amount of oxygen produced by a plant. Glucose is a product of the photosynthesis process and does not impact the production of oxygen.

Conclusion

To increase the production of oxygen in plants, the amount of available carbon dioxide should be increased. Carbon dioxide is a key reactant in the photosynthesis process, which produces oxygen as a byproduct. Other factors such as glucose do not directly influence the production of oxygen in the photosynthesis process.
