The oxygen produced as a byproduct of photosynthesis is released into the atmosphere. 

During the process of photosynthesis, green plants, algae, and some bacteria use light energy to convert carbon dioxide and water into glucose, a type of sugar that serves as a source of energy and building material for the organism. As a byproduct of this process, oxygen is released into the atmosphere. The oxygen produced in this process diffuses out of the chloroplasts and into the atmosphere, where it is available for use by other organisms. This process is vital for life on Earth, as it provides the primary source of oxygen for almost all living organisms.
