Question
Usually, carbon dioxide in the range of ___________ is adequate for photosynthesis.
- 30-40 PPM
- 300 – 400 PPM
- 500-600 PPM
- 50-60 PPM
Hint:
Higher concentration of CO2 increased the rate of photosynthesis
The correct answer is: 500-600 PPM
- Higher concentration of carbondioxide helps in increasing the rate of photosynthesis
- Usually carbondioxide in the range of 300- 400 ppm is adequate for photosynthesis
- Increased carbondioxide production increases oxygen production
