NEET BIOLOGY

Detailed explanation-1: -Elevated [CO2] causes increased photosynthesis in plants, which leads to greater production of carbohydrates and biomass.

Detailed explanation-2: -Photosynthesis increases as CO2 increases until some saturating concentration, which is typically around 1, 000 ppm. Enriching the air with CO2 enables plants to more effectively utilize light, resulting in an increase in the light saturation point.

Detailed explanation-3: -However, once the light intensity gets high enough, the rate won’t increase anymore because there will other factors that are limiting the rate of photosynthesis. A limiting factor could be the amount of chlorophyll molecules that are absorbing the light.
