In one year lightning produces how much amount of usable nitrogen fertilizer?

  1. $250000 tons$

  2. $25000 tons$

  3. $250 tons$

  4. $25 tons$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$Answer:-$ A

The processes of the nitrogen cycle transform nitrogen from one form to another. Atmospheric nitrogen must be processed, or fixed, in a usable form to be taken up by plants. Between $5\times 10^{12}$ and $10\times 10^{12}$ g per year are fixed by lightning strikes.
