Answer: We can live without food for a week, without water a day or two, but without breathing? Not more than a minute. All of us are alive because we breathe, not just humans, but plants and animals also breathe.
Explanation: Breathing is a mechanical Process. In breathing, an organism takes in oxygen from its environment and released carbon- dioxide.Breathing involves the transport of oxygen and carbon dioxide between the external environment and the body cells. This process is also called pulmonary respiration.
Organisms carry out external respiration in various ways depending on their size and environment. For example, exchange of oxygen and carbon dioxide happens directly with the environment through any cell membrane. In human beings and some animals, lungs are the chief organs of breathing.
