if not from the atmosphere , they must depend on a process called nitrogen fixation.
They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
Nitrogen is not very reactive
Nitrogen is everywhere But somehow, nitrogen has to get from the atmosphere into a form that our body can use.I also think that nitrogen in soil can be used by plants not animals

Nitrogen gas in the soil is used by plants, which are eaten by animals. The waste products of the animals contain the nitrogen. It is broken down by bacteria, which releases nitrogen gas into the atmosphere, and the cycle repeats.
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.
Nitrogen is the most abundant element in the Earth's atmosphere. Bacteria in the soil 'fix' the nitrogen gas into compounds which can be taken in by plants; the plants get eaten by animals & they use the nitrogen to make proteins.
nitrogen comes to the soil from atmosphere through lightening plants getthis nitrogen from the root nodules or collect it themselves . Animals eat these plants and get this nitrogen and again this animal is killed by other one and the nitrogen passes to it this process continues like a cycle
Animals such as deer eat plants that contain nitrogen. The nitrogen helps the animals build and repair cells. When that animal dies, the nitrogen is released back into 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.
Nitrogen fixing bacteria will enable some plants to convert atmospheric oxygen to a form that can be used by plants. The plants are then eaten by animals.
Nitrogen is returned to the atmosphere through the process of denitrification, where bacteria convert nitrates in the soil back into nitrogen gas. This process completes the nitrogen cycle as nitrogen is released back into the atmosphere as a gas.
