Animals ingest nitrogen in nitrate-containing food after plants use nitrogen containing compounds.

The organic matter decays via decomposers.

N molecules breaking apart via nitrogen fixing bacteria.

N2 is formed via denitrifying bacteria.

Explanation:

Plants utilizes nitrogen compounds with the help of roots. Afterwards these plants serves as source of food for the animals. When both plant or animal dies the decomposing bacteria acts upon to breakdown the complex organic remains of plants and animals into ammonia, which is then subjected to the process of nitrification. Here the ammonia is converted into nitrites and nitrates respectively. Then it is acted upon by denitrifying bacteria and the nitrates and converted into gaseous form of nitrogen.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
