→ Plants makes their own food by the process of photosynthesis and makes the oxygen through it. Animals can consume oxygen through the respiration process. Plants also consume oxygen for respiration but the produce oxygen more than they consume. Hence there is balance between oxygen and carbon dioxide production with the help of plants and animals hence they are depending on each other for respiration.
Q.16.) Give the composition of air ?

Q.17.) Make a list of five activities occurs due to presence of air?
→
- Respiration – use of oxygen and carbon dioxide in air
- Burning- oxygen helps in burning
- Photosynthesis- Carbondale oxide is used in respiration and oxygen is get produced as a product.
- Flying of birds
- Movement of parachutes and airplanes.
Q.18.) define pollution and give causes of air pollution ?
→ Pollution is the addition of some harmful gases in the atmosphere that are harmful to human beings,plants and animals.

→
- As pollution of air contain many harmful gases that are being respired by human beings , plants and animals May cause death. So, to avoid this we must take some efforts to decrease air pollution.
- We must use vehicles as less as possible. We can use electric vehicles as that is no use of any petroleum substances and hence no any harmful gases coming out.
- We must increase the use of bicycle than the vehicles use petroleum substances.
- By planting more and more trees, we can decrease the air pollution.
- Plastic if burn causes harmful gases so we can recycle the use of plastic.
