Answer: There will be less amount of oxygen produced by the plant.
Step-by-step explanation:
The process of photosynthesis requires carbon dioxide, water and most importantly sunlight in order to convert light energy to chemical energy.
The process releases oxygen in the environment and if the intensity of the light is reduced then the rate of photosynthesis will also decrease.
In this case the rate of oxygen produced will also decrease. So, light is a very important factor when it comes to photosynthesis.
