It's a process called photosynthesis. You're probably thinking, what in the world is photosynthesis? Well I'll tell you! Most life on earth actually depends on photosynthesis. Plants, algae, and some types of bacteria all use photosynthesis. Basically, the plants, algae, etc. all create sugar and oxygen from carbon dioxide, water, and sunlight. Carbon dioxide, light, water goes in. Glucose, water and oxygen come out. Basically, how we live all depends on photosynthesis. Because if we didn't have photosynthesis, then we wouldn't have plants. And if we didn't have plants then we wouldn't have herbivores (animals that only eat plants), and if we didn't have herbivores then we wouldn't have food for us to eat.
