why do animals breathe


Asked by pavithrajambula22 31st March 2019, 2:46 PM

All animals, on this earth need oxygen for living, and respiration is a mandatory for carrying out the process of breathing. The carbon dioxide is exhaled out from the body as waste which in turn is taken up by the plants for survival.
