Question

The light intensity, at which the photosynthesis intake of CO2 is equal to the respiratory output of CO2.

Answer 1

As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rateincreases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration.

Answer 2

As light intensity raises, the rate of photosynthesis will be raised as long as other factors are in sufficient supply.

Explanation:

• As the rate is high, eventually another factor will come into less supply.
• The graph below reveals the effect of less carbon dioxide concentration.
• If carbon dioxide and light levels are more, but temperature is small, increasing temperature will have the highest effect on reaching a higher rate of photosynthesis.
