Explanation:

Nitrogen is present in the soil. The plants take up nitrogen along with other minerals as they draw water from the soil. Nitrogen enters the soil when decomposers feed on dead and decaying matter. They breakdown nitrogen and release it into the soil. The plants take this nitrogen from the soil.

The area labelled X shows that nitrogen is present in the air. Nitrogen is one of the abundant gases which is found in the Earth's atmosphere.
