      • The Process of photosynthesis takes up Carbon dioxide and release oxygen. <\/strong>Hence photosynthesis does not add carbon dioxide to the carbon cycle.<\/li>\n\n\n\n
      • Volcanic action<\/strong> leads to the release of Carbon dioxide.<\/li>\n\n\n\n
      • Respiration <\/strong>is the movement of oxygen from the outside environment to the cells within tissues and the release of carbon dioxide in the opposite direction. <\/li>\n\n\n\n
      • The process of decomposition<\/strong> releases Carbon dioxide.<\/li>\n<\/ul>\n\n\n\n
        Carbon cycle<\/h6>\n\n\n\n
          \n
        • Carbon cycle shows the movement of carbon in elemental and combined states on earth<\/strong>. Diamond and graphite are the elemental forms of carbon and in a combined state, it is found as carbonates in minerals and as carbon dioxide gas in the atmosphere.<\/li>\n\n\n\n
        • Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.<\/li>\n\n\n\n
        • Carbon Cycle Steps<\/strong>\n
            \n
          • Carbon present in the atmosphere is absorbed by plants <\/strong>for photosynthesis.<\/strong><\/li>\n\n\n\n
          • These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.<\/li>\n\n\n\n
          • These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.<\/li>\n\n\n\n
          • Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.<\/li>\n\n\n\n
          • These fossil fuels are then used for man-made activities, which pump more carbon back into the atmosphere.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
