What is the main global reservoir of nitrogen?

Video transcript

Welcome back. Let's look at our next question. It says which one contains the highest percentage of nitrogen? Well, nitrogen is found in the largest reserves in the atmosphere And in fact about 78% of the air we breathe is nitrogen. So when we look for the highest percent among the answer choices, um we see our choices are water, soil, air or land choice. Sea air is going to be our correct answer due to that abundance of nitrogen in the atmosphere. And looking at the other answer choices Choice. A water, be soil and D land. All these will be minor sources of nitrogen. You have both things like ammonia nitrate and nitrates found in those that can be sources of nitrogen, but again, the atmosphere particularly rich in nitrogen gas and therefore has the highest percent of nitrogen. See you in the next video.
