Without a nitrogen cycle that converts atmospheric nitrogen into other compounds, living creatures would not be able to grow. Maybe only some primitive bacteria may still be alive without the nitrogen cycle, but any plant life would not be possible. Nitrogen is used to build DNA, the basis of our life.
What would happen if there was no nitrogen cycle?

What happens when nitrogen is removed from the atmosphere?
Specifically, bacteria in the soil convert nitrogen into nitrates, nitrites and other important compounds that are essential to plant life. With all the nitrogen removed from the atmosphere, this has an immediate effect on the nitrogen cycle, and of course us humans, since the entire food chain depends on plants.
Why is nitrogen needed for life on Earth?
Nitrogen is needed to create amino acids which in turn build proteins in all plants and animals. Without a nitrogen cycle that converts atmospheric nitrogen into other compounds, living creatures would not be able to grow.
Can plants survive without nitrogen in the atmosphere?
So neither plants,trees nor humans can survive without nitrogen …. Every air or rather oxygen breathnig organism would die due to over oxygenisation, since the now void of nitogen atmosphere would have an near 3 times larger concentration. , I'm a science teacher - this literally IS my day job.
Can there be life without nitrogen?
Life can exist without oxygen, but without plentiful nitrogen to build genes – essential to viruses, bacteria and all other organisms – life on the early Earth would have been scarce. The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago.
Why do we need nitrogen?
Your body needs nitrogen to make proteins in your muscles, skin, blood, hair, nails and DNA. You obtain nitrogen from protein-containing foods in your diet, according to the Royal Society of Chemistry. These foods include meat, fish, legumes, nuts, eggs, milk and other dairy products.
