I WILL MARK BRAINLIEST! PLEASE HELP ME!

Hey the question isn't clearly visible

but the picture explains the Nytrogen cycle

Explanation:

The water droplets/rain dissolves the fertilizers and make it easier for the plant to suck it.The bacteria present in the roots of the plant takes up the nitrogen and helps the plant to grow.The cow eats the plant and the nitrogen is in the cow's body.After some years the cow dies and its body is eaten up by animals and when it decays, the nitrogen in its body mixes with the earth and thus is taken up by plants and used. The plant gives out air and vapours containing nitrogen through transpiration and other processes which then results in the release and mixing of nitrogen with other gases and thus resulting in rain.

Hope you got it... :)
