Herbivores, like all consumer organisms, obtain their component atoms from the food they ingest. They cannot obtain Nitrogen from air (even though the air is about 78% nitrogen). Nitrogen is a key atom in all proteins - as part of the "amine" group in the "amino-acid" that makes up the backbone of all protein chains. This amino acid usually remains intact once digested, to be used to create new proteins that the herbivore might need for its own purposes.
Plants take in nitrogen from their roots then the consumers eat the plants.
photosynthesis
Nitrogen is consumed by different organisms in different ways. Legumes (a type of plant) are able to take nitrogen straight out of the atmosphere (which is roughly 78% nitrogen gas). Animals aren't able to do this so they must obtain their nitrogen by eating substances such as vegetables and meat. We break down proteins (largely from meat) down to their constituents which are amino acids. This is how we obtain our source of nitrogen (amino acids contain nitrogen atoms). We then use these amino acids to build proteins that we need in our body such as tissue, enzymes, antibodies and more.
The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen". Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.
At the very basic level all DNA needs nitrogen. WIthout DNA there is no life.they need it to live
mostly from food.
Some plants are leguminous and have root nodules by which they are able to directly absorb the nitrogen from the atmosphere. If the are not leguminous, they get the nitrogen from the soils via their roots. For the same purpose of supplying nitrogen to the plants, farmers also add nitrogenous fertilizers to the soil which provides sufficient amount of nitrogen to the plants
Animals obtain nitrogen by eating plants which have absorbed nitrogen from the soil.
Plants take in nitrogen from their roots then the consumers eat the plants.
Either ammonium nitrite or ammonium dichromate can he heated to obtain nitrogen gas.
from food. Mainly by cleaving proteins and nucleic acids from food.
No.

Unless they are legumes, from the soil.
