Correct answers: respiration; burning of fossil fuels; decomposition of organic waste.

Explanation: respiration (by animals, microbes, plants) and decomposition release CO2 (or CH4 in anaerobic conditions) back to the atmosphere. Burning fossil fuels also releases CO2. Photosynthesis removes CO2 from the atmosphere (so it is not a return process).
