Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia.
All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.

Air contain nitrogen, oxygen, other minor noble gases, ozone, carbon dioxide water vapors, fumes, powders.
What is cn2 in the atmosphere?
CN2 in the atmosphere is not an actuality. The 'C' stands for carbon, but there is no carbon in the atmosphere, carbon is not a gas. N2 stands for nitrogen. There is nitrogen in the air. Perhaps it is CO2 that needs more clarification. CO2 is Carbon Dioxide. There is carbon dioxide in the air because that is what humans give off when they exhale. Plants need this to survive.
How does carbon and nitrogen affect the atmosphere?
Carbon affects the atmosphere when humans burn fossil fuels into the air and other chemicals
Where is nitrogen found in?

How much nitrogen does humans breathe out?
78% 0of the air we breathe is nitrogen, same as the amount in the air.
Where do humans get nitrogen in there diet?
nitrogen can be found in plants and meats, but also majority of the air we breathe is made up of nitrogen.
How do humans add nitrogen to the atmosphere?
by breathing co2 back into the air. Therfore magically making it nitrogen.
How do humans add nitrogen to the air?
Through manufacture and use of fertilizers.
Animals can use nitrogen only if it is in the form of?
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
How do humans and animals get nitrogen?
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
How is nitrogen found and made?
70% of our air is nitrogen, it's an element, and doesn't need to be made
Which gas exist in air that your body needs to survive?
Of all the gases in the atmosphere that you need to survive, oxygen is the one but you also need nitrogen which you don't use like you use oxygen but it does keep your lungs inflated.
What must happen before humans can use nitrogen?
For humans to be able to use nitrogen it must be converted from N2 (g) to ammonium (NH4^+), nitrate (NO3^-), or organic nitrogen. Nitrogen is the majority of the air we breath but it is relatively inert due to the triple bond between N atoms.
How do humans breathe Oxygen?
Yes. The air is 21% oxygen which is what humans run on. It is 79% nitrogen which we filter out. I learned this today in Health class.
What do humans need that is not on the moon?
air
Can most orgnisims get nitrogen gas from the air?
animals dont really need nitrogen but for plants, they need nitrogen and they get nitrogen usually in the form of nitrates or bacteria protein, by the work of nitrifying bacteria, putrefying bacteria and nitrogen fixing bacteria
