#Section 5: Applied Ecology & Evolution
  1. C   plants are more efficient in their use of CO2
  2. C   plants are able to obtain the same amount of CO2 by keeping their stomata open for shorter periods of time.
  3. C4 plants don’t use CO2 as their source of carbon.
  4. C3 plants are more limited than C4 plants by CO2 availability because of transpirational water loss.
