Photosynthesis is NOT a process that releases carbon back into the environment. Instead, it is a process by which plants absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen using sunlight. The other processes listed—burning of carbon-based fuels, decomposition of dead organisms, and cellular respiration—do release carbon back into the environment.
