give examples to show that air is important for survival of living organisms

Air is a mixture of many gases, such as nitrogen, oxygen, carbon dioxide. These gases are important as it provides oxygen for respiration process to occur in animals and provides carbon dioxide to green plants for photosynthesis to takes place.
Taking example of green plants, they use carbon dioxide together with water and sunlight to produce energy and make their own food to survive. This process is known as photosynthesis which give out oxygen as a by product which in turn needed by almost all animals to survive.
