The Nitrogen Fixation Cycle: Presented by Dr. Undergrad.

Dr. Undergrad presents a basic introduction to the Nitrogen Fixation Cycle. In this cycle nitrogen is fixated to become more biologically available to the organisms of the world. Nitrogen from the atmosphere will be fixated into a nitrate or the ammonium ion. Once fixated there are a number of processes that the fixated nitrogen can undergo to pass through the cycle until it returns back to the atmosphere. This video was made for a contest hosted by http://www.chlorofilms.org. Special thanks to Dr. Adán Colón-Carmona for suggesting the nitrogen cycle as a topic for the new animation.

The video is useful. However there is one correction..yes Ammonium carries a positive charge, but nitrate should be carrying a negative charge.

@alelmnoor

You are correct. I left the postive charges on the Nitrogen atoms,

and did not include the total formal charges of the whole molecules. Sorry for the confusion. You have a good eye for detail.

@TheMsAlegna The 'offensive violence' adds an element of humour which incourages students to learn it + It is appropriate because it showed the Lion being decomposed
