It might be eaten by a carnivore and its protein will be catabolised (broken down) and absorbed to make new proteins in the carnivore. It might be decomposed by bacteria after death. Perhaps after decomposition it will be broken down and taken up by a plant (if the nitrogen in it has been fixed) and then the plant may use it.

Here's a link for the nitrogen cycle that has a diagram. \nhttp://muextension.missouri.edu/xplor/envqual/wq0252.htm\nBasically nitrogen goes from plants to animals to the ground from waste and is broken down by bacteria.\n\nHere's a good link that explains the phosphorous cycle. Basically, the phosphorous cycle is when phosphorous is in water from broken down rock sediment and in plants, is consumed and used in animal, then is returned to the environment through decomposers.\n\nThe carbon cycle is when carbon from the air is used by plants and animals in respiration and returned to the environment in respiration and decomposition.\n\nHere's another link that may help.\nhttp://neptune.gsfc.nasa.gov/STAFF/brianc/phospho.html

Protein?\n\nOnly thing I could come up with-do you have any letters?

For the population density of say, a large sauropod, which were chiefly herbivorous, they would have had to consume extreme amounts of high energy foods to grow fast.  Since plants require a massive metabolism to digest, their metabolism must have been very slow, which in turn means that they grew slowly.  \n\nA carnivore like your garden variety t-rex, which was also very large, would have had a faster metabolism because he ate (supposedly) large quantities of protein, but still, every organism´s metabolism is dictated by the same rules, so t-rexes must have been slow too, thus indicating that they also grew up pretty slow (considering their size of course).

Yes, we can obtain protein and even vitamin B12 from plant produce such as beans and soya products. The original diet was fruits and after the fall God instructed man that the herbs of the field would be meat for him to eat. It was not until after the Noah's flood that you had meat eating. Thou shalt not kill (murder) i believe also goes for the animals too which we should take care of.

Picture a string of beads- the beads are different sizes and shapes. \n\nNow, "proteins" are basically like a string of beads that could be a very long string or a short string. AND instead of beads, there are amino acids- with different shapes and sizes. \n\nBut these strings don't lie flat. Depending upon the amino acids and other factors, the protein strings bend and fold in certain ways. So the string may become more like a ball or other strange shapes; this affects the way the protein works and interacts with other protein or chemicals. \n\nHope that mental picture helps answer your question...

It doesn't.  Eating protein foods increases protein.  Exercise uses this protein to build muscles.

Listen carefully and ignor anyone who tells you diffrently. All the informaton needed for every protien in the body is stored as DNA. When a particular protien is needed, the streatch of DNA that codes for it is copied into RNA. THis piece of RNA is called a transcript. \n\nThe transcript is usually proccessed in the cell before being sent to the ribosom. There the ribosom reads the nucleic acids in groups of three. So no one nucleic acid makes a protien, but three nucleic acids determine one amino acid. A string of amino acids makes up a protien.

>>>>>(IT IS NOT HOMEWORK! i am competing with a friend for the >>>>> best example)\n\nAnd cheating by asking strangers on the internet. I like the way you think.\n\nThe most extreme example of bacterial endosymbiosis amongst mammals is without a doubt the presence of mitochondria. You might not relaise it but mitochondria are stable line bacterial endosymbionts, complete with there own genetic structure. It's hard to top that.\n\nAfter that probably comes the entire rumen structure of ruminants. Its incredibly cmmplicated, but basically the stomach of cows and sheep is one massive bacterial fermentor. The cow eats grass but is totally unable to digest it. Instead it grinds the grass up fine and swallow sit to wet it. It leave sit in the stomach to fermenta while then brings it up to shew again after the bacteria have softened it. The food then goes back down for even more fermentation in the other three chambers of the stomach. To add to the elegance of this system cows don't just excrete their urea through their kidneys like other mammals. Urea is  a waste in mammals and is poisonous, but it is also a good fertiliser. Ruminants excrete their urea through their salivary glands. It then passes into the stomach and what was a poison to the cow becomes fertiliser for the bacetria, who convert the waste urea into protein that the cow can use. As a reuslt ruminants are the only mammals in the world tht can survive with no protein input intheir deit at all. Which explains why they have been so extraordinarily successful at surviving in harsh and low nutrient environments.\n\nLast comes the biosynthesis of vitamins. Mammals can't   make their own vitamins, they normally need to take it in on the food. However numerous mammals species from dogs to horses are able to harvest those vitamins from bacteria that grow in their guts. So although a dog lives on a diet that is horrendously deficient in 3 or four vitamins it never gets ill or needs to take vitamin tablets. Which is pretty clever.

What is nitrogen used for? \n    Nitrogen is a component of many organic molecules.  It forms an essential part of amino acids (which make up proteins) and DNA.  Nitrogen is essential for all living cells. \n\nWhat is the nitrogen cycle? \n    Nitrogen is the major component of earth's atmosphere.  It enters the food chain by means of nitrogen-fixing bacteria and algae in the soil.  This nitrogen which has been 'fixed' is now available for plants to absorb.  These types of bacteria form a symbiotic relationship with legumes--these types of plants are very useful because the nitrogen fixation enriches the soil and acts as a 'natural' fertilizer.  The nitrogen-fixing bacteria form nitrates out of the atmospheric nitrogen which can be taken up and dissolved in soil water by the roots of plants.  Then, the nitrates are incorporated by the plants to form proteins, which can then be spread through the food chain.  When organisms excrete wastes, nitrogen is released into the environment.  Also, whenever an organism dies, decomposers break down the corpse into nitrogen in the form of ammonia.  This nitrogen can then be used again by nitrifying bacteria to fix nitrogen for the plants.

Charles Darwin proposed that the first proteins evolved from non-living matter. But how did this happen? Firstly, the earth was not the same today as it was 3 to 4 billion years ago when the first organic compounds where being formed. The early atmosphere was too hot for oxygen (O), nitrogen (N), and other elements to exist alone, as they do today. These elements combined to form methane (CH4), ammonia (NH3), water vapor (H2O), hydrogen sulfide (formula), hydrogen molecules (H2), etc. These where all, and thus the early atmosphere was called a 'reducing atmosphere'. Further, as there was no free oxygen to form an ozone (O3) layer to protect the earth from the harsh ultra-violet radiation (UV Rays) from the sun. Also, there where incredibly violent electrical storms, which where more violent than any which occur today. \n\nIn 1924 Alexander Oparin hypothesized that organic compounds where formed in the early earth when the high energy provided by UV Rays, and storms, caused different molecules to react, and create new organic compounds, such as Amino Acids DNA, and RNA.

Good question.  \n\nThe first thing you need to realise is that all living things contain some protein. Grass doesn’t contain much protein but it does contain a bit. To boost the amount of protein cattle get many places also sow their pasture with legumes like clover. Legumes contain  lot more protein than grass and that helps the cows a lot.\n\nBut the really clever part of the way that cows conserve protein. When most animals have proteins that are no longer needed, such as form worn out cells, the body strips the nitrogen off it and recycles the rest as food. The nitrogen then gets excreted in the urine as urea. Cattle don’t do that. If their diet becomes low in protein cattle will excrete the urea in their saliva instead of their urine. The urea goes straight into the stomach, and the bacteria their use it to make protein. So even though the grass a cow eats is often very low in protein the cow itself gets a lot of high protein food form the microbes. The cow is quite literally fertilising the microbes with nitrogen.\n\nFarmers have recently learned how to turn that to their advantage. If the pasture protein content drops farmers can feed their cattle urea fertiliser. Exactly the same urea fertiliser you buy for your garden. Although urea isn’t protein itself it allows the cattle to make protein. So even when eating low protein feed the cattle still put on weight so long as they are being fed fertiliser.\n\nAddenda\n\nGsshulkte said "ruminants have the ability to turn nitrogen\n>>>>>>>>> into protein. so when they eat legumes like \n>>>>>>>>>alfalfa and grains they can convert it into useable \n>>>>>>>>>protein. \n\nAny nitrogen in alfalfa or grains will already be in useable protein form.  That is why humans can and often do obtain all their protein requirements from a diet of alfaflfa and grains. There is no requirement to convert it and cattle have no advantage over any other animal using such foods as a protein source.\n\nSAMI said "Cows ...convert the carbohydrate in grass \n>>>>>(called CELLULOSE ) ...and use it for energy,fat and\n>>>>> protein the same way as humans.\n\nSami that is totally wrong. \n\nFirtsly humans cant use cellulose at all. It is totally indigestible to use. In human nutrition we refer to cellulose as dietary fibre becuse it is indigestible. It passes through as a fibrous mass with no benefit to us at all.\n\nSecondly it is simply  impossible to use a carbohydrate like cellulose for a protien. Carbohydrates lack nitrogen, which is a crucial component of proteins.

Nitrogen is the key element which gives proteins their functionality. The body needs proteins to build and repair tissues. Animals get these proteins from plants who get it from the air. The nitrogen in the air also keeps us from bursting due to excessive respiration.
