Which of the following process(es) release ${\mathrm{CO}}_2$ in , atmosphere?

Therefore, during the process of cellular respiration, carbon dioxide is released into the atmosphere. During decomposition, carbon dioxide is released into the atmosphere. The primary cause of the growing carbon levels in our atmosphere is human interference in the carbon cycle through the burning of fossil fuels. The chemical process of calcination results in the direct emissions of cement. When limestone, which is composed of calcium carbonate, is heated, calcium oxide and carbon dioxide are produced.
