Trees do contain nitrogen because they contain protein (the density of protein in plants is less than in animals, but plants still need some protein to carry out their various biochemical processes).
Yes, plants do store nitrogen. Plants have the ability to take up several chemical forms of nitrogen, and absorb it from the soil.
Yes. Nitrogen is an essential part of chlorophyll, and we know that chlorophyll is vital for photosynthesis.
They absorb nitrogen through their roots.
No. Nitrogen gas is fairly inert.
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
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.
Nitrogen-Fixing bacteria. aka Rhizobium
It's nitrogen fission of course
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
Plant can not use nitrogen "air" (gas), it must be "fixed" , a nitrous compound.
It is very close to it, being about 78.09%.
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
mycorrhizae
Because they don't want to.
nitrogen fission
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Fixes nitrogen
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.
