Hey there Rk Naresh! Look, when it comes to plants and animals, they're not exactly partying with atmospheric nitrogen. Plants typically need nitrogen in a more accessible form, like nitrates or ammonium, which they get from the soil. Animals get their nitrogen by munching on plants or other animals that have already done the hard work of nitrogen assimilation.

Now, on the global warming front, nitrogen itself doesn't directly cause global warming. However, human activities, like burning fossil fuels and certain agricultural practices, release nitrogen compounds into the atmosphere. These compounds, like nitrous oxide, can contribute to the greenhouse effect, which plays a role in warming the planet. So, it's not the nitrogen's fault per se, but how we handle it can stir up some trouble.
