Question

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?
A) In a response to the drought, stomata will open more frequently. There will be higher outputs of CO2 and O2 as a result.
B) An increase in temperature will cause an increase in chemical activity. There will be increases in all chemical inputs and outputs in the model.
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.
Eliminate
D) Water will be a limiting reactant in the model. There will be less H2O in through the roots and less H2O out via transpiration. The other inputs and outputs will remain constant.

Answer 1

The answer would be C

Answer 2

IM pretty sure that its c.
