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 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.
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.
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.
Animals get nitrogen from plants.
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.
Animals will lose nitrogen when they die. This is whey decay and nitrogen is released as ammonia into the air.
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.
If you are told it is a fact that animals do not need nitrogen, you can infer that you are receiving incorrect information. All living things require nitrogen. However, animals are not able to obtain the nitrogen they need directly, but must get it from their food, and that comes ultimately from the plants that are able to absorb nitrogen from the soil.
well, herbivores eat plants (which have nitrogen in them due to help from nitrogen fixating bacteria) then other animals eat herbivores. Since animals are heterotrophs they have to get their nutrients from other organisms.
The human body is about 3% Nitrogen
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.
