How do living things use air?
Air is important for living things. Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide. This process gives animals and plants the energy to eat, grow, and live life!
How do different living organisms breathe air?
Respiration in animals This happens when animals move air into and out of their lungs, or by flapping their gills if living in water. When animals breathe in, they take in oxygen and when they breathe out, carbon dioxide is removed from the body.
How does body use air to breathe?
Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body’s doesn’t need. To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm. Your diaphragm tightens and flattens, allowing you to suck air into your lungs.
Why do living organisms need air?
All living things need oxygen (air) to survive. During the respiration process, all the living things take oxygen from the air and give out carbon dioxide. It is vital that all living things inhale oxygen in order to make the living cells function properly.

What is in air we breathe?
Air is mostly gas The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
What does a living thing breathe in?
oxygen
All living organisms, plants and animals breathe in oxygen and breathe out carbon dioxide.
Why do organisms breathe?
All living things need oxygen. The oxygen reacts (or combines) with food you eat to make energy. The reason living things breathe is to get the oxygen they need, and to get rid of carbon dioxide waste. Plants and animals breathe in many different ways.
