Step-by-step explanation:
If carbon dioxide (CO2) is completely removed from a plant's environment, the plant's production of high energy sugars would decrease or stop.
This is because carbon dioxide is a critical component of the process of photosynthesis, which is how plants produce high-energy sugars (such as glucose) that they use as a source of energy. During photosynthesis, carbon dioxide is combined with water in the presence of light energy to produce glucose and oxygen.
If there is no carbon dioxide available, the plant will not be able to produce glucose through photosynthesis, and therefore will not have the energy it needs to survive and grow. In fact, plants that are deprived of carbon dioxide will typically begin to exhibit stunted growth, yellowing of leaves, and other signs of stress or damage.
