Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.

Why can't animals use nitrogen in the air?
Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil cuz bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria a.k.a. blue-green algae transform the nitrogen from the atmosphere into usable forms of nitrate
What form must nitrogen take before plants and animals can use it?
through roots from the soil
What must happen to nitrogen before plants and animal can use it?
Nitrogen must be in the compound form before it is used by plants or animals
Plant and animals can not use the nitrogen that makes up?
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
What is the only form of nitrogen that nonlegume plants can take in and use?
photosynthesis
Do animals use nitrogen?
no
Do animals take in nitrogen directly from the atmosphere?
Since 78.08% of the Earth's atmosphere is composed of nitrogen, yes. But it cannot be used in biological processes. The nitrogen animals use comes in the form of nitrogen compounds acquired from food. Ultimately, the nitrogen used by most living things is produced by nitrogen-fixing bacteria which do use nitrogen from the atmosphere, these compounds are then taken in and used by plants.
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
What elements are most organisms unable to take from the atmosphere?
nitrogen
Is it true although 78 percent of air is nitrogen plants cannot use this form well?
It is very close to it, being about 78.09%.
What must happen for plants to use nitrogen in the atmosphere?
Fixation
Why is nitrogen fixation important to living things?
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).
