Answer:
Plants absorb carbondioxide gas from atmosphere whereas respiration releases carbondioxide .
Explanation:
Carbon is present in the atmosphere in the form of carbondioxide gas which is used by the plants in the process of photosynthesis. Plants takes carbondioxide gas from the surrounding air through small openings called stomata and made their own food while on the other hand, carbondioxide gas is released from the body of living organisms in the process of cellular respiration. In cellular respiration, food is broken down with the help of oxygen forming water, carbondioxide gas and energy in the form of ATP molecules.
