Much like humans, animals go through a process of metabolic waste to rid themselves of the toxins in their system. Some of the chemicals animals get rid of include nitrogen, phosphates, sulfates, water, and uric acid.

What do animals use nitrogen for?
The same reason humans do. People breath oxygen and nitrogen.
What do humans and animals exhale when they release carbon back in the air?
CO2 (carbon dioxide).
How is Nitrogen stored in the biosphere?
The largest store of nitrogen is atmosphere, where it exists as nitrogen gas. Other major stores of nitrogen includes oceans and organic matter in soil.
When do animals lose nitrogen?
Animals will lose nitrogen when they die. This is whey decay and nitrogen is released as ammonia into the air.
How do herbivores obtain the nitrogen they need?
Herbivores obtain nitrogen just like any other animal - through the air, which is mostly composed of nitrogen. However, organic nitrogen that can be used in proteins is only found in autotrophs. Through the nitrogen cycle, atmospheric nitrogen is fixed as organic nitrogen which is assimilated by plants. Herbivores, like omnivores and carnivores, get their nitrogen from food. The trick is getting the nitrogen "fixed" into the food in the first place. About 80% of earth's atmosphere is nitrogen, but atmospheric nitrogen is very nearly inert (the triple bond between the nitrogen atoms is difficult to break). It does not readily engage in chemical reactions, so plants and animals cannot get their nitrogen by breathing. Oxygen, on the other hand, reacts easily, so you'll find that you can get the oxygen you need directly from the atmosphere. Plants extract carbon directly from the atmosphere--from carbon dioxide and photosynthesis. That carbon, plus water and some other ingredients, produce the carbohydrates and other nutrients we get from plants. But like us, plants can't capture atmospheric nitrogen. They have to get the nitrogen they need for proteins & DNA from another source. So how does nitrogen get fixed into plants? Primarily via nitrogen compounds in the soil. There is a bit of nitrogen in any soil, thanks to decaying plants & animals and the activity of certain types of bacteria. But if you farm the soil intensively, you can quickly exhaust the naturally occurring nitrogen. One way to build up the nitrogen in soil is to exploit a symbiotic relationship between certain types of bacteria and a few types of plants. Bacteria that grow on the roots of some bean plants convert atmospheric nitrogen into compounds that stay in the soil. This is the phenomenon behind crop rotation with soy beans--you let the bacteria on the soy bean's root replenish the nitrogen in the soil. Then crops you grow in that soil pass that nitrogen through the food chain. For example, an herbivore might eat the crop directly, or a carnivore could eat the flesh of an herbivore that ate the crop that grew in the field that once grew soy beans that hosted nitrogen-fixing bacteria. Another way to get the nitrogen into the soil is via animal waste. Manure contains a good deal of fixed nitrogen. Hence the smell that bothers city folk when they visit farm country. Today, a good deal of the nitrogen in crops comes from manufactured fertilizer. The Haber-Bosch chemical process, developed about a hundred years ago, draws nitrogen from the air and fixes it in forms that can be used for fertilizer (or explosives.) About half of the nitrogen in your body came from the atmosphere via the Haber-Bosch process. (See "The Alchemy of Air" by Thomas Hager, 2008, for more on the history of Haber-Bosch.) Without Haber-Bosch, a couple billion of us humans would not be alive.
How has the element nitrogen helped humans?
Nitrogen help humans in diffrent ways
How has humans intruded on the nitrogen cycle?
The disposing of sewage into water is one way humans interfere with the nitrogen cycle. Humans are also responsible for releasing large amounts of NOx gasses into the atmosphere, which interferes with the nitrogen cycle as well.
How do humans use nitrogen?
Humans use nitrogen in the form of proteins. Bacteria found in soil convert atmospheric nitrogen into nitrates that plants use to produce proteins.
How do humans add nitrogen to the biosphere?
Humans add nitrogen to the biosphere in the form of nitrate, a major component of plant fertilizer.
What do animals use nitrogen for?
The same reason humans do. People breath oxygen and nitrogen.
What are the risks of nitrogen to the human body?
It is possible for humans to suffocate and die in pure nitrogen.
What do humans do that provides nitrogen to our to our gardens?
fertilizer
How do humans get nitrogen they need?
By eating plants
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.
Which two gases in exhaust fumes are harmful for humans?
The two gases in exhaust fumes that are harmful to humans are carbon monoxide and nitrogen. Nitrogen is not as dangerous as the carbon monoxide, because the atmosphere is about 78% nitrogen.
What gas is formed during respiration?
The gas that is formed during respiration is carbon dioxide. Humans breathe in a mixture of nitrogen, oxygen and carbon dioxide. Although, only oxygen is used. When humans exhale they release all of the nitrogen and more carbon dioxide than was inhaled.
Are humans part of the nitrogen cycle?
Yes. All living things are part of the nitrogen cycle.
