The same reason humans do. People breath oxygen and nitrogen.
Animals will lose nitrogen when they die. This is whey decay and nitrogen is released as ammonia into the air.
Nitrogen is required by plants and animals for protein synthesis
Animals obtain nitrogen primarily through the consumption of plants or other animals that contain nitrogen-containing compounds, such as proteins. They break down these compounds during digestion and reuse the nitrogen to build their own proteins and other essential molecules.
Nitrogen is essential for animals to build proteins, which are crucial for growth, repair, and maintenance of body tissues. Nitrogen is a key component of amino acids, the building blocks of proteins. Without sufficient nitrogen, animals would not be able to carry out vital functions for survival.
.They get it from eating plants.
no
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.
Oxygen keeps animals alive, Nitrogen is not much use.
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.
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
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.
Animals get nitrogen from plants.
Animals obtain the nitrogen needed to make proteins and nucleic acids by consuming foods that contain nitrogen, such as plants or other animals. The nitrogen is then broken down and used by the body to build the necessary molecules for growth and repair.
Nitrogen must be in the form of ammonium (NH4+) or nitrate (NO3-) before plants and animals can use it for growth and development. These forms of nitrogen can be taken up by plant roots and further utilized in biological processes.
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.
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.
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
