Hi there! I'm Dan!
And i'm kelly!
we're going to teach you about the nitrogen cycle!
It all starts in the soil, when bacteria absorb the atmospheric nitrogen(NH2), and turn it into ammonia. This process is called nitrogen fixation.
Decaying Plant and animal remains can also create ammonia.
After this the legumes in the plants roots turn the ammonia into nitrates.
atmospheric and industrial fixation creates nitrates directly into the soil.
The plant absorbs most of the nitrates, but some get denitrified by bacteria and gets put back into the atmosphere.
Thanks for listening!
