Can someone plz explain the Nitrogen cycle???
In the nitrogen cycle, all of the nitrogen comes from the atmosphere. It is unusable to plants in the form in the atmosphere, so bacteria in the ground end up “fixing” nitrogen to a usable form, I think the usable form is NO3, but i’m not sure. Anyways, there’s two ways for nitrogen from the atmosphere to be used. One is through lightning driven reactions and the other one as previously mentioned is from bacteria in the ground and in the ocean. Now, humans have also been taking nitrogen from the atmosphere and “fixing” it like bacteria do. We use it for fertilizer and other things like that. Humans have become a large part of the nitrogen cycle. We have fixed so much nitrogen that we have almost equaled natural means of fixing nitrogen. This is a problem because you know what they say about too much of a good thing. Nitrogen ends up making ecosystems way more productive, this ends up especially being a problem in the ocean where “dead zones” (areas with little oxygen) and harmful algae
