Detailed explanation-1: -The Process of photosynthesis takes up Carbon dioxide and release oxygen. Hence photosynthesis does not add carbon dioxide to the carbon cycle.
Detailed explanation-2: -So, the correct option is ‘Photosynthesis by producers’.
Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
Detailed explanation-4: -Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
Detailed explanation-5: -Volcanic action, Respiration and Decay of organic matter adds carbon dioxide to the carbon cycle on the planet Earth.
