All living things respire. They cannot live without respiration because it is a vital process. During this process air is taken into the lungs the nose and expelled through the month.
The oxygen in the air is carried by blood to each and every cell in the body where it combines chemically with the digested food. As a result of this process energy and carbon dioxide are produced. The energy thus released is utilized to perform different activities, for example work, motion,growth etc.
The process of respiration is very conspicuous in animals if you put your hand on your chest you can feel your chest heaving during breathing. Plants also respire but you cannot see them respiring. Very small pores called stomata are present on the under surface of leaves. It is through these pores that exchange of gases takes place in the plants.
Now look at the non-living things present around you. Do they breathe?.
