the nitrogen is released back into the environment.
It is taken in as gaseous nitrogen from the atmosphere (which we breathe), and expelled into the environment through nitrogenous wastes (i.e. urine).
Used for amino acid and protein synthesis... excreted in urine as ammonia. Excreted in fecal material as well.
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
The same reason humans do. People breath oxygen and nitrogen.
Nitrogen helps animals to build amino acids inside their bodies. These acids are essential for making proteins which are vital for the body.
eating the plants
nitrogen in the soil is used by both plants and 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
Ammonia
sodium
Excess nitrogen is made into uric acid and excreted.
it is used by plants and animals
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.
Well, most of the Nitrogen in an organism's body is excreted as urine, urea or ammonia.
Animals get nitrogen from plants.
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.
gas
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.
