What happens to the rate of photosynthesis as the intensity of light or concentration of CO2 increases? And How is your conclusion from the question above different from what happens as temperature increases?

The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.

Explanation:

Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.

An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.

the answer for this question would be d. glaciers

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
