Question
If the rate of respiration becomes more than the rate of photosynthesis, plants will:
Options
continue to live, but will not be able to store food
be killed instantly
grow more vigorously because more energy will be available
stop growing and die gradually of starvation

Solution
stop growing and die gradually of starvation
Explanation:
When the rate of respiration exceeds the rate of photosynthesis, the plant will stop growing and gradually die of starvation. Initially, the plant will rely on its stored food reserves to meet its energy needs. However, if this imbalance continues, these food reserves will eventually be depleted, leading to the plant’s eventual death.
