Detailed explanation-1: -During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

Detailed explanation-2: -Animals use oxygen in the process of respiration and make more CO2.

Detailed explanation-3: -During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

Detailed explanation-4: -Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-5: -Humans and other animals obtain oxygen for cellular respiration through breathing. The oxygen you breathe is used to break down the nutrients you consume through food in order to make ATP, while carbon dioxide and water are generated as waste products.
