How does the relation of atmospheric CO2 with photosynthesis prevent it from being called only a pollutant?
Answer and explanation
Correct answer: Because plants use it in food formation
Carbon dioxide has a dual environmental role. Green plants absorb CO2 during photosynthesis and use carbon, water, and light energy to make glucose, releasing oxygen as a by-product. Therefore, CO2 is a natural and essential atmospheric gas, not merely a pollutant. However, excessive human-caused CO2 strengthens the greenhouse effect and can cause warming. Option A states the relevant reason; the other choices are unrelated or false.
