Which of the following are two major limiting factors of photosynthesis?

• Carbon dioxide concentration and temperature

• Temperature and oxygen concentration

• Oxygen concentration and carbon dioxide concentration

Why can photosynthesis not occur at very high temperatures?

• Because carbon dioxide concentration is lower

• Because enzyme activity is lower

• Because light intensity is lower

Which limiting factor of photosynthesis is likely to have the greatest effect on plants growing in an open field during a hot summer day?

• Carbon dioxide concentration

• Light intensity

• Temperature
