• Fixation: Consists in the transformation of gaseous nitrogen into substances usable by living beings (ammonia and nitrate). The organisms responsible for fixing are bacteria, they remove nitrogen from the air causing it to react with hydrogen to form ammonia. • Ammonification: Part of the ammonia present in the soil is originated by the fixation process. The other comes from the process of decomposing proteins and other nitrogenous residues, contained in dead organic matter and excreta. Decomposition or ammonification is carried out by bacteria and fungi. • Nitrification: It is the name given to the process of converting ammonia into nitrates. • Denitrification: Denitrifying bacteria (such as Pseudomonas denitrificans) are capable of converting nitrates into molecular nitrogen, which returns to the atmosphere, closing the cycle.

don't be discouraged, i know how it feels but things will get better <3
Now I'm feeling soooooo down because of what he said. It sticks in my head for the whole day! I keep thinking that I could have done better if I had chosen to do my best. I already made a new version, but I didn't had time to finish it, so I let it be and went with the first version. But what if I finished the second version and we presented that. Won't I feel less down?
