The rate of photosynthesis decreases as the
|
|
oxygen concentration decreases
|
|
|
carbon dioxide concentration decreases
|
|
|
light intensity increases
|
|
|
temperature becomes moderately warm
|
Explanation:
Detailed explanation-1: -As it is normally present in the atmosphere at very low concentrations (about 0.04%), increasing carbon dioxide concentration causes a rapid rise in the rate of photosynthesis, which eventually plateaus when the maximum rate of fixation is reached.
Detailed explanation-2: -Photosynthesis can be influenced by several factors some of these factors are light intensity, temperature, water supply, and the concentration of carbon dioxide. If the temperature and light intensity is too high or low, there is an immediate decline in the rate of photosynthesis.
