Quizplus · Accepted Answer

Green plants and algae are primary producers of oxygen through photosynthesis. If they were all destroyed, the existing oxygen reserves in the atmosphere would be depleted as they are consumed by animals and various processes. Studies, including a report by the National Center for Biotechnology Information (NCBI), suggest that the current levels of oxygen in the atmosphere could sustain life for about a decade before the levels drop to a point where animal life would start to suffocate.
