The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
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.
Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.
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.
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.
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.
Plants and animals obtain nitrogen from the soil and other organic sources. Nitrogen-fixing bacteria in the soil convert atmospheric nitrogen into forms that plants can absorb, such as ammonium and nitrate. Additionally, animals acquire nitrogen by consuming plants or other animals, incorporating it into their own bodies through the food chain. Decomposers also play a vital role by breaking down organic matter, returning nitrogen to the soil for plant use.

no
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.
During nitrogen fixation, certain bacteria convert atmospheric nitrogen into a form that plants can use, like ammonia. This process helps make nitrogen available for plant growth, which then enters the food chain as animals consume plants. Overall, nitrogen fixation is essential for maintaining the balance of nitrogen in ecosystems and supporting plant growth.
Animals use nitrogen to build proteins in their bodies. Nitrogen is a vital component of amino acids, which are the building blocks of proteins essential for growth, maintenance, and repair of tissues in animals.
Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use. This contributes to the nitrogen cycle by making nitrogen available for plant growth, which then gets passed on to animals and eventually returns to the soil through decomposition, completing the cycle.
Because the nitrogen in the air is in a form not usable to animals and plants. The only way animals get nitrogen to build protein and nucleic acid is by eating it. This is usually through plants, which get there nitrogen from the soil. They get it from the soil cuz bacteria in the soil turn the atmospheric nitrogen into a usable form. In a water ecosystem cyanobacteria a.k.a. blue-green algae transform the nitrogen from the atmosphere into usable forms of nitrate
The reduction of nitrate to gaseous nitrogen. Most plants cannot use atmospheric(gaseous) nitrogen. It must be "fixed" by bacteria in the ground. Plants use nitrogen in the forms of ammonia(NH4+) and nitrate ions(NO3-). source: http://ohioline.osu.edu/aex-fact/0463.html

The key reason is to help them make proteinsAmino acids make up proteins, and one of the things which makes up amino acids is nitrogenProteins are used for the growth of the plant, and also the repair and replacement of parts of the plant when it is damaged
