1.	Plants use carbon dioxide from air for photosynthesis. How is the carbon dioxide in airreplaced?
Answer» <p>During photosynthesis, cells use carbon dioxide and radiation from the Sun to produce sugar molecules and oxygen. These sugar molecules are converted to more complex molecules such as glucose. The respiration process comes next, in which the cells use oxygen and glucose to synthesize carrier molecules that are rich in energy, such as 'Adenosine triphosphate' or ATP, and carbon dioxide is produced as a waste product. Therefore, the synthesis of glucose and its breakdown by cells are opposing processes. The entire cycle - building and breaking of carbon-based material — from carbon dioxide to complex organic molecules and returning to carbon dioxide — is part of the 'global carbon cycle'.</p>
