A major source of oxygen for the Earth's atmosphere is?

Plants photosynthesise to produce oxygen. They also act as a carbon sink. I suppose the largest source of oxygen on Earth is the Amazon forest in South America. Amazon forest is five and a half million square kilometers (1.4 billion acres) big. It is currently the world's most important carbon sink. The Amazon forest is estimated to produce 20% of the world's oxygen supply, excluding all the other plants (e.g. grass). For that, I suppose this is the largest source of oxygen on our planet.
