The production of ammonia by bacteria during the decay of nitrogen-containing urea is called nitrogen cycle. The process of combining nitrogen gas with hydrogen to form ammonia is called nitrogen fixation.
Ammonia can be found in the water when either animal waste or a decaying animals nitrogen is converted by bacteria in a process call ammonification.
The three types of bacteria which are involved in the nitrogen cycle are nitrogen- fixing bacteria which change the nitrogen gas into ammonia. The next is nitrifying bacteria which changes the ammonia into nitrities and then the nitriites into nitrates. Then the plant absorbs the nitrates and uses them to continue growth. Then an animal may eat the plant receiving the nitrogen from it. But it must eventually get ride of it so it produces waste which goes back into the soil and is broken down by decomposers and fungi, which then turn it back into ammonia. The cycle then repeats itself. Extra nitrates are turned back into nitrogen gas by denitrifying bacteria.
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.
The nitrogen found in the animal returns to the soil
Protein is a macronutrient that we get from food. It is made up of Carbon, Hydrogen, Oxygen, and Nitrogen. Proteins are the body's only source of nitrogen. When we ingest a protein containging food we excrete the nitrogen in our urine; it is called urea.
When an Animal Dies, and Decomposes Nitrogen is Released, where Bacteria and Plants begin there work, you may want to research the Nitrogen Cyclean animal returns nitrogen to the environment when it urinates or decompeses or dies or decays
hydrogen
you can get it at your local Petland or ace hardware but if you are referring to where ammonia comes naturally, then ammonia is a common byproduct of animal waste due to the often inefficient conversion of feed nitrogen (N) to animal product (Bicudo et al., 2002). Livestock and poultry are often given high protein feed containing surplus N to meet the animals' nutritional requirements. N that is not metabolized into animal product (i.e., milk, meat, or eggs) is excreted in feces as NH3, urea, and organic N and in urine as urea (in mammals) or uric acid (in birds).
...Dear lord. Okay. Nitrogen (dinitrogen - N2) is the most abundant molecule in our atmosphere. However, since it has a bond order of three and very strong bonds at that, it is generally useless. There are certain organisms, called nitrogen - fixing bacteria, though, that can convert nitrogen to ammonia (NH3). Ammonia is usable by plants, who incorporate it into amino acids, etc. and nitrate (NO3-). When animals eat the plants, they use these prefabricated molecules for themselves. This travels up the food chain. Finally, when an animal dies, bacteria break down the fixed nitrogen back to N2 and the process starts all over again.
this is a very hard question i don't even know we are learning this in 8th grade too
