Detailed explanation-1: -In respiration, the by-products are water and carbon dioxide molecules produced by the breakdown of carbohydrates.

Detailed explanation-2: -Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.

Detailed explanation-3: -The products of cellular respiration are energy (or ATP), carbon dioxide, and water. The products of respiration or breathing, come from the reactions of cellular respiration. In animals, carbon dioxide is transported back to the lungs through the blood and exhaled through exhalation.

Detailed explanation-4: -Water is formed when hydrogen and oxygen react to form H2O during the electron transport chain, which is the final stage of cellular respiration.

Detailed explanation-5: -The products and reactants for photosynthesis are reversed in cellular respiration: The reactants of photosynthesis are carbon dioxide and water, which are the products of cellular respiration. The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis.
