Nitrifying bacteria participate in the nitrogen cycle mainly by a. converting nitrogen gas to ammonia. b. releasing ammonium from organic compounds, thus returning it to the soil. c. converting ammonium to nitrate, which plants absorb. d. incorporating nitrogen into amino acids and organic compounds.

Hello everyone. And in this video we have the following problem. The reduced form of nitrogen in the soil known as blank is transformed into its most oxidized form by night refining bacteria present in the soil. And this process all it's doing is describing nitrous fication which is a process by which the least oxidized form of nitrogen, meaning that it contains at least oxygen in its molecular formula which is ammonia. As we can see here is going to be converted into nitrate which is the most oxidized form because it contains the most oxygen in its molecular formula. As we can see here and comparing nitrate to another form of nitrogen like nitrate. We're going to see that it contains much more oxygen. It is the most oxidized form. And so notification involves the conversion of ammonia into nitrate. And as we can see the only answer choice that represents this change or this process is going to be answer choice C. So the reduced form of nitrogen in the soil known as ammonia is transformed into its most oxidized form nitrates by the night refining bacteria present in the soil. That is going to be how we complete the statement. And that is the end to our video. Thank you very much and I hope to see you on the next one
