Question

Which would have the GREATEST effect on the rate of photosynthesis in a plant?

Answer 1

If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.

Answer 2

Answer: Low level of carbon dioxide, low temperature due to lack of sunlight will affect the process of photosynthesis.

Step-by-step explanation:

The photosynthesis can be defined as the process by which autotrophs make their own food in the presence of sunlight with the help of carbon dioxide, water and other nutrients presents in soil.

If there will be inadequate amount of sunlight, or low level of carbon dioxide then the rate of photosynthesis will decrease.
