It doesn't. Nitrogen in its natural gaseous state is triple bonded and not broken down by plants or animals. Nitrogen must be fixed by bacteria the live symbioticly with plants so that the plants can use the nitrogen. ( the bacteria get sugar in this process ) Animals then get their nitrogen from consuming plants and other animals.
when animals eat plants,they get nitrogen compounds that their bodies need.plants do not make these nitrogen compounds. so from where do plants get their nitrogen compounds/ from the air
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
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 fixation is the process by which bacteria remove nitrogen from the air and make it available to plants.
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.

From plants or air.
A lot of comes from the air. The air you breathe is around 78 percent nitrogen, so nitrogen enters your body with every breath. Rhizobium bacteria is present in leguminous plants in their roots which extract nitrogen from the soil. These are generally present in dicot-seed plants. When you consume these plants, nitrogen enters your body. Another way that nitrogen enters the body is through eating meat. When animals eat plants, those plants have nitrate in them which contains nitrogen so the animals have nitrogen in them now. Then, humans eat the meat from the animals, adding some nitrogen to our bodies.
All animals and plants. The air is 78% nitrogen.
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
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.
decomposition, because once animals or plants die, the nitrogen is then returned to the air.
nitrogen cycle
Nitrogen can enter the soil from plants such as legumes which fix nitrogen in their roots. Also dead plants and animals add nitrogen into the soil.
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
