Can nitrogen be directly used by living things?
no nitrogen can not directly use for living
What do all living things use nitrogen to?
Nitrogen is a main component of our DNA, which is the genetics material of all living organisms.
All living things use nitrogen to?
make proteins.
What does Rhizobium radicicola help plants use from the air?
Fixes nitrogen
What uses nitrogen?
All living things use nitrogen to build amino acids, nucleic acids, and ATP.
What is nitrogen changed into before being used by living things?
lightning & bacterial action (nitrogen fixers).
Would living things be able to use nitrogen if lightning did not fix it?
Yes, only an extremely small amount of reduced nitrogen is fixed by lightning.
Can we use pure nitrogen gas as a nutrient?
No, not directly. There are bacteria that can fix Nitrogen out of the air and make it available as a nutrient but Nitrogen has to be in a compound form for it to be useful to most of the living things on Earth.
Do most organisms use nitrogen in the form of nitrogen gas?
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
How do rhizobacteria help plants?
Plants can not use atmospheric nitrogen. Rhizobacteria fixes atmospheric nitrogen into nitrate.plant can utilize nitrate in their metabolism.thus fertility of the soil is maintained.
What is azotobacter chrococcum?
It fixes atmospheric nitrogen for crop use and produces other plant growth promoting substances
although air is full of nitrogen, it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?
AMMONIA, NITRATES AND NITRITES
