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
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.
They use the nitrogen in the food they eat to form their bodies, particularly proteins. They throw out excess nitrogen with the help of excretion, and their bodies are decomposed after death into various forms of nitrogen, too.
When animals or plants die, the nitrogen in their tissues is broken down by decomposers like bacteria and fungi. This process releases nitrogen back into the soil in the form of ammonium. Some of this nitrogen can be taken up by plants through their roots to use for growth, while excess nitrogen can be converted into nitrate and enter the groundwater system.
Nitrogen enters plants primarily through the soil in the form of nitrates and ammonium, which are produced by the decomposition of organic matter and through nitrogen-fixing bacteria that convert atmospheric nitrogen into usable forms. Plants absorb these nitrogen compounds through their roots, incorporating them into amino acids and proteins. Animals obtain nitrogen by consuming plants or other animals, thereby integrating the nitrogen into their own biological systems. This nitrogen cycle is crucial for maintaining healthy ecosystems and supporting life.
Nitrogen must be in the compound form before it is used by plants or animals
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 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.
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.

We get the nitrogen our bodies need by eating food.
Plants and animals cannot directly use atmospheric nitrogen (N2 gas) for their growth and development. Instead, certain bacteria in the soil or in the roots of plants can convert atmospheric nitrogen into a form that plants can absorb, such as nitrate or ammonium. Plants then take up these nitrogen compounds through their roots and use them to build proteins and other essential molecules. Animals obtain nitrogen by consuming plants or other animals that have already incorporated nitrogen into their tissues.
Fixation
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.
Nitrogen fixation is important because it converts atmospheric nitrogen into a form that plants can use to grow and thrive. This makes nitrogen available to animals through the consumption of plants that have been able to utilize fixed nitrogen. Ultimately, nitrogen fixation helps sustain the food chain and ecosystem health.
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.
They use the nitrogen in the food they eat to form their bodies, particularly proteins. They throw out excess nitrogen with the help of excretion, and their bodies are decomposed after death into various forms of nitrogen, too.
