उत्तर
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.
