what is mean by oxygen hoe is it useful to us how is it grown ​

Answer 1

Oxygen : Oxygen is a gas that you cannot see, taste or smell. Plants and animals cannot live without oxygen.

Use : Oxygen is used by animals and plants in the respiration (breathing) process. Tanks of oxygen are used in medicine to treat people with breathing problems. They are also used as life support for astronauts and scuba divers. The majority of the oxygen used in industry is used in the manufacturing of steel.

Growing : Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process, in which animals convert oxygen in the air back into carbon dioxide.
