Detailed explanation-1: -A plant is exposed to an optimum amount of light intensity, with a limited supply of CO2. As the carbon dioxide, concentration increases the rate of photosynthesis increases.

Detailed explanation-2: -Light intensity-Increasing light intensity increases the rate of photosynthesis because more energy is provided. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor (such as temperature) is limiting the rate of the reaction.

Detailed explanation-3: -Light intensity: Though the plant gets water and carbon dioxide, it can’t photosynthesize without light. Increasing the light intensity will raise the rate of photosynthesis.
