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

∙ 11y agoThe nitrogen has to be converted in the soil. Nitrogen in it's air form doesn't react to many things, so plant's can't use the form in the air.

Animals can use nitrogen only if it is in the form of?
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
What are the uses of Oxygen and Nitrogen in air?
Oxygen keeps animals alive, Nitrogen is not much use.
Can animals use nitrogen directly from the atmosphere?
no plants and animals cannot use nitrogen straight out of the air every time we take a breath you breath it in but it goes through nitrogen fixation to let us humans animals and plants to use it.
How does nitrogen from the air get into the bodies of plants and animals?
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
Do animals use nitrogen?
no
What converts nitrogen into air plants can use?
Plant can not use nitrogen "air" (gas), it must be "fixed" , a nitrous compound.
Should I use air or nitrogen in tires?
air
Is it okay to put regular air on nitrogen tires?
Yes, you can use nitrogen or plain air.
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.
Why doesn't the humans breathe nitrogen?
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 because 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
Explain why levels of nitrogen are why levels of nitrogen are the same in air breathed in as air breathed out?
Because the body does not use the nitrogen in any way.
What do animals use nitrogen for?
The same reason humans do. People breath oxygen and nitrogen.
