Answer 2

Answer: The most abundant has in the atmosphere is NItrogen.

Step-by-step explanation:

Nitrogen is the most important gas in the atmosphere, it's account for about 78% of total gas in the atmosphere.

Plants cannot absorb nitrogen directly from the atmosphere it most first be converted to soluble ions because nitrogen gas is unreactive. Nitrogen is converted to nitrate by nitrogen fixing bacteria in the soil, through root nodules of leguminous plants and lightening. In this form, plants absorb nitrogen and use it to make chlorophyii. Chlorophyii is an essential pigment in green plants needed for photosynthesis.
