Does respiration uses carbon dioxide and produce oxygen energy?

No, respiration does not use carbon dioxide and produce oxygen energy. The process you described is photosynthesis, which is performed by plants and certain bacteria. In photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Respiration, on the other hand, is the process by which organisms use oxygen to break down glucose and produce energy in the form of ATP (adenosine triphosphate). During respiration, oxygen is consumed, and carbon dioxide and water are produced as waste products.
