Detailed explanation-1: -Answer. Explanation:Since carbon dioxide is needed in photosynthesis process, then much of the carbon dioxide which is produced by green plants is not always excreted in form of metabolic waste because it can be easily used in the photosynthesis process.
Detailed explanation-2: -Carbon dioxide is waste generated by the metabolic process of cellular respiration. Cellular respiration uses nutrients like glucose along with oxygen and converts these molecules into carbon dioxide and water. This process releases energy that is transferred to a molecule called ATP.
Detailed explanation-3: -Six oxygen molecule is released as a waste product. This oxygen is produced due to splitting of water by the process of photolysis during light reaction. So, the correct answer is option ‘Oxygen’.
Detailed explanation-4: -Oxygen is a metabolic waste product from photosynthesis and carbon dioxide is a metabolic waste product produced through cellular respiration.
Detailed explanation-5: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
