What must happen for pure nitrogen in the air to be able to be us eby plants/ A. Photosynthesis B. Fixation C. Precession D. Respiration
Fixation
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
through roots from the soil
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.
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 must be in the compound form before it is used by plants or animals
Fixation
Fixation
Fixation
Because elemental nitrogen is unusable by plants. It must be converted in the soil to a usable form and adsorbed by soil particles for plants to be able to utilize it.
Carnivorous plants must rely on insects for nitrogen since they are found in soils with low nitrogen levels. Since the soil can't provide them with enough nitrogen, they must consume insects to meet their nitrogen requirements.
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
For humans to be able to use nitrogen it must be converted from N2 (g) to ammonium (NH4^+), nitrate (NO3^-), or organic nitrogen. Nitrogen is the majority of the air we breath but it is relatively inert due to the triple bond between N atoms.
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
