In the carbon cycle, carbon is removed from the atmosphere primarily through the process of photosynthesis. During photosynthesis, plants absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen using sunlight. The other processes listed (respiration, decomposition of organic waste, and burning of fossil fuels) either release carbon dioxide into the atmosphere or do not significantly remove it.
