Hi friends....
Explin what is composition of the atmosphere?

Answer 1

$\huge \mathbb{hello}$
$\large \mathfrak{your \: answer}$
Nitrogen and oxygen are two gases which make up the bulk of the atmosphere. carbon dioxide, helium, ozone,argon and hydrogen are found in lesser quantities. apart from these gases tiny dust particles are also present in the air.
nitrogen is the most plentiful gas in the air. when we inhale, ridiculous amount of nitrogen into out lungs and exhale it. bud plants need nitrogen for their survival. they cannot take nitrogen directly from the air. bacteria that live in the soil and root of some plants take nitrogen from the air and change its form so that plants can use it.
oxygen is the second most plentiful gas in the air. humans and animals take oxygen from the air is breathe. green plants produce oxygen during photosynthesis. in this where oxygen contain in the air remains constant. if we could trees then disbalance get Disturbed.
carbon dioxide is another important gas. green plants use carbon dioxide to make their food and release oxygen. humans or animals release carbon dioxide. the amount of carbon dioxide released by humans and or animals seems to be equal to the amount used by the plants which make a perfect balance. how I learned the balance is upset by burning of fuels, such a coal and oil . dead billion of tone of carbon dioxide into the atmosphere each year. SNL recent increase volume of carbon dioxide is affecting the Earth's weather and climate.
