Question

1.mention the gases present in air
2.which gas is 0.033% in air ? how does it help the plants?
3.which gas is essential for survival of all living organisms ? what is it's percentage in atmosphere ?
4. how does this water vapour come From into the atmosphere ?if so, how? is it useful to us​

Answer 1

1. Oxygen , Carbon dioxide , Hydrogen , Nitrogen .

2. Carbon dioxide is 0.033 % in air . It help plants in making food .

3. oxygen is important for all living organism to survive .

4. Water vapour come in air from evaporation . This help in rain and rainwater we drink .


Hope it will help u
Thank u

Answer 2

Here is your answer
______________________________
1. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

2. Carbon dioxide

Role in plants:

Carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration. Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. ... Like Oxygen, Carbon Dioxide in the atmosphere is necessary for life to exist on Earth.

3. Oxygen — 21 percent

4. As a greenhouse gas, the higher concentration of water vapor is then able to absorb more thermal IR energy radiated from the Earth, thus further warming the atmosphere. The warmer atmosphere can then hold more water vapor and so on and so on. This is referred to as a 'positive feedback loop'.
