Why is nitrogen fixation important to living things?

Answer 1

Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).

Answer 2

it is important because nitrogen-fixing bacteria change nitrogen into a usable form for animals and plants

we animals need that nitrogen but cannot use it unless it has been processed by nitrogen-fixing bavteria

Answer 3

nitrogen fixation is very important coz it helps in d decomposing ofdeads and decays..and it increases the fertility of soil....nitrogen is a must for fertile soil and healthy agriculture...hence we spray nitrogen fertilisers in crops....theres a long list of importance of nitrogen...from the DNA to beans and pulses...nitrogen is present....:)

most organisms can't use nitrogen in the form it takes in the atmosphere

Answer 4

Plants can not fix atmospheric nitrogen, break it down from its strong triple bonds, so they need symbiots to do this for them. Nitrogen is a basic material needed by all life. Think of manufacturing nitrogenous bases for example.

Answer 5

Because it helps plants and Animals make Protein.

Answer 6

nitrogen fixation is important not only to animals but also to us, humans because it is responsible for the cycle of air. it turns a useless air into useful air that living organisms benefit.
