Detailed explanation-1: -Carbon dioxide is converted to organic carbon through photosynthesis by primary producers such as plants, bacteria, and algae. Some organic carbon is returned to the atmosphere as CO2 during respiration. The rest of the organic carbon may cycle from organism to organism through the food chain.

Detailed explanation-2: -Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands, and forests. Plants and the soil then release carbon dioxide when they decay. Other organisms also release carbon dioxide as they live and die.

Detailed explanation-3: -For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.

Detailed explanation-4: -Photosynthesis, Decomposition, Respiration and Combustion. Carbon cycles from the atmosphere into plants and living things. For example, carbon is a pollutant in the atmosphere as carbon dioxide.

Detailed explanation-5: -The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
