Where do animals get there nitrogen from?

Question

Where do animals get there nitrogen from?

Answer 1

Animals get there nitrogen basically from proteins. All proteins are derived from amino acids which contain nitrogen groups. Through several reaction nitrogen is extracted from these proteins.

Other organisms such some of the bacteria get there nitrogen via fixing it from the air, the process is called nitrogen fixing.Plants get there nitrogen by association with these nitrogen fixing  bacteria.

Answer 2

protein? Protein has nitrogen in them, and can be found in meat of some animals or some beans.

Answer 3

1. Nitrogen fixation by microorganisms and with the help of plants leads to food chain in ecosystem and animals feeding plants will get nitrogen from plant food. Other carnivorus animals also get nitrogen from these vegetarians. Protien, oils , chlorophyll etc has nitrogen.The ultimate source is Air.

Answer 4

Now now, you shouldn't end your questions/sentences with a preposition.

And they get it from eating plants.  Plants get it from pulling nutrients out of the soil.  The soil gets it from decaying animals.  There's a pattern there if you look close enough...

Answer 5

Nitrogen from air is fixed into the plant roots by bacteria like Rhizobium and plants take up ammonium and nitrate salts already present in soil.

This nitrogen is made use by plants to make protoplasm and many of their parts

Plants are eaten by some animals and some other animals eat animals eating plants .

nitogen flows thus from Plants  ->  animals-> other animals and reach every body
