Sunlight!!!

Although the above answer is correct, I guess there could be some explaining. You see, sunlight powers and starts the photosynthesis. Plants absorb carbon dioxide and release oxygen. Here's something that will help, sunlight is the source for all energy. Even us. We need to breath to live. Plants give us oxygen to breath. Plants use sunlight to give us oxygen. So, the answer to any question involving the source of anything is always sunlight.
