Why do organisms need nitrogen?

Answer 1

for amino acid production and the fact that pure oxygen is just too reactive.(so isn't just so fortunate that air is about 78% nitrogen??)

Answer 2

It also has another important service to man. Consider that the earth is a space craft on a very long trip. Oxygen is essential to your life, 20.9% is nominal. Plus and minus 1.5 %. as many things combined to other chemicals it will not be long before we are in trouble.How is it controlled? That is cloister than I have Sean before .
The secrete is that Nitrogen when bombarded with alfa particles in the high altitude trans mutate to Oxygen. So instead of 21.9 % there is 78% that will automatically change to oxygen when the ozone layer gets too thin.
Boy the Eng. sure knew his stuff to make all this happen.

Answer 3

The main reason why organisms need Nitrogen is because without nitrogen, organisms would not be existed because they would have no DNA or RNA.

Answer 4

Nitrogen is an essential part of amino acids. Every organism needs amino acids.

Answer 5

Do a internet seek for legumes and soil progression. Clover, alfalfa, peas, and beans are examples of legumes. those vegetation host micro organism of their roots that extract nitrogen from the air and grant it to their host vegetation so as that the vegetation can build their very own protein. Farmers in many cases inoculate their legume seeds with the micro organism earlier planting. That way they harvest protein wealthy vegetation or fertilize their floor by plowing those vegetation returned into the floor so as that that's going to be obtainable for regardless of money crop they plant next.

Answer 6

nitrogen helps to build amino acids which in turn help to make protein. Some bodybuilders use it for faster rebuilding of muscule tissue to increase their repair rate. But thats only for organisms with muscule tissues
