Photosynthesis plays a vital role in our environment. The whole life form is directly or indirectly dependent on the process of photosynthesis carried out by plants. If photosynthesis does not occur in plants then plants cannot synthesize the food. This causes the mbalanv=ce in the environment. The plants will not produce oxygen and then no animal life will be able to survive due to the absence of oxygen. We will not get oxygen, food, and life on this planet will be extinct.
