Answer:
The correct answer will be option-
1. Carbon dioxide concentration
2. Light intensity
Explanation:
A limiting factor is a factor which when present in the limited amount limits the metabolic process.
Photosynthesis is a complex process which converts the light energy to the chemical energy converting the carbon dioxide in the presence of sunlight to useful chemical metabolites like glucose.
The photosynthesis process is limited by the concentration of carbon dioxide and light intensity.
The low concentration of carbon dioxide and low light intensity availability decrease the rate of photosynthesis.
Thus, the selected options are correct.
