Please briefly describe the impact of oxygen, nitrogen, water vapor, ozone, carbon dioxide and other gases on human production and life?

Oxygen: necessary for all life, oxidation obtains heat energy to sustain life, and determines the combustion, decay and decomposition processes of organic matter. Nitrogen: dilutes oxygen so that the oxygen is not too concentrated and the oxidation is not too intense. It is a nutrient for plants, etc. Water vapor: an important role in weather changes, source of fresh water, water cycle, all life is inseparable from water, etc. Ozone: absorbs ultraviolet rays from the sun, protects organisms on earth from ultraviolet burns, affects the vertical distribution of atmospheric temperature, etc. Carbon dioxide: greenhouse gas, important substance in photosynthesis, etc.
