Question

describe nitrogen assimilation...............

Answer 1

$\huge\star\mathfrak\pink{{Answer:-}}$

Nitrogen assimilation :

In soil, nitrogen is present as nitrates,

nitrites and ammonia (NH4+). It is obsorbed by

the green plants and converted to nitrogenous

organic compounds like amino acids, DNA,

etc. This is known as nitrogen assimilation.

From plants, nitrogen as biomolecules like

amino acids, enters food chain and moves to

animals and then to decomposers through the

death of animals.

Nitrates are first converted to ammonia

but it is highly toxic and immediately used

for conversion into amino acids, which are

then transported to other parts of the plants for

synthesis of proteins.

Answer 2

Answer:

Nitrogen Assimilation

Explanation:

Nitrogen Assimilation is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compoinds present in the environment. Organisms like plants,fungi and certain bacteria that cannot fix nitrogen gas(N2) depend on the ability to assimilate nitrate or ammonia for their needs.
