Explanation:
Detailed explanation-1: -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-2: -Cellular respiration converts ingested nutrients in the form of glucose (C6H12O6) and oxygen to energy in the form of adenosine triphosphate (ATP). CO2 is produced as a byproduct of this reaction. The O2 needed for cellular respiration is obtained via inhalation.
Detailed explanation-3: -The study shows that across the world, carbon release by plant respiration may be around 30% higher than previously predicted.
