|
If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars (rate of photosynthesis)?
|
|
Sugar production will likely increase.
|
|
|
Sugars will not be produced.
|
|
|
The rate of sugar production will decrease .
|
|
|
Fewer sugars will be produced at first, but then the plant will recover.

Explanation:
Detailed explanation-1: -The same number of sugars will be produced but without carbon dioxide. Carbon dioxide does not affect the production of high-energy sugars in plants.
Detailed explanation-2: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.
Detailed explanation-3: -1 Answer. The rate of photosynthesis will decrease as the amount of CO2 decreases.
