Why do organisms need respiration?
Answer and explanation
Correct answer: To obtain energy
Respiration is a vital life process in which food molecules such as glucose are broken down, with or without oxygen, to release usable energy. Cells use this energy for movement, growth, repair, transport and other activities. Thus option A is correct. Colouring the body, removing undigested food and sleeping are not the main purposes of respiration.
