The model above shows the metabolic processes occurring in green plants. Plants use sunlight, plus carbon dioxide and water to produce glucose. The by-product of photosynthesis is oxygen, which is added to our atmosphere. Plants also respire; creating ATP, the energy they need to continue to grow, develop and reproduce. Imagine it is summer; there is a drought. How will the summer drought influence the model we see here? Responses A In a response to the drought, stomata will open more frequently. There will be higher outputs of CO2 and O2 as a result.In a response to the drought, stomata will open more frequently. There will be higher outputs of CO 2 and O 2 as a result.

C Water will be a limiting reactant in the model. As a result, less glucose will be produced. There will be less CO2 in and O2 and H2O out.
The correct answer is C: Water will be a limiting reactant in the model. As a result, less glucose will be produced. There will be less CO2 in and O2 and H2O out.
During a summer drought, there is a shortage of water available to plants. As a result, water becomes a limiting reactant in the model. This means that the amount of water will be insufficient for the metabolic processes to occur at their usual rate. Consequently, there will be less glucose produced by the plants.
In addition, since plants will have less water available, the stomata (small openings on the surface of leaves) will close to prevent water loss through transpiration. This, in turn, will reduce the intake of carbon dioxide (CO2) and the output of oxygen (O2) as a by-product of photosynthesis. Additionally, with less water available, there will be a decrease in the output of water (H2O) through transpiration.
Therefore, the correct response is C: Water will be a limiting reactant in the model. As a result, less glucose will be produced. There will be less CO2 in and O2 and H2O out.
The correct answer is C: Water will be a limiting reactant in the model. As a result, less glucose will be produced. There will be less CO2 in and O2 and H2O out.
During a summer drought, there is limited water available to the plants. This scarcity of water affects the metabolic processes in the model above. In the process of photosynthesis, plants use water (H2O) as one of the reactants. Since water is limited, the production of glucose will be reduced. As a result, there will be less carbon dioxide (CO2) being taken in by the plants, and the release of oxygen (O2) into the atmosphere will also be reduced.
Additionally, water plays a role in transpiration, which is the process of water vapor escaping from the leaves of plants. During a drought, plants will have less water to transpire, and consequently, there will be a decrease in the amount of water (H2O) being released from the plant through transpiration.
Therefore, option C accurately describes the influence of a summer drought on the model.
