At the very basic level all DNA needs nitrogen. WIthout DNA there is no life.
they need it to live
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.
The nitrogen cycle begins with the decomposition of dead animals, which releases nitrogen into the soil. Nitrogen-fixing bacteria convert atmospheric nitrogen into forms that plants can absorb. Once in the soil, nitrogen moves into plant material as plants take up these nutrients. Finally, when plants and animals die or excrete waste, nitrogen is returned to the atmosphere as gaseous nitrogen through processes like denitrification, completing the cycle.
All plants need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Bacteria living in plant nodules in the soil on the roots of the plant also provide the plant with the nitrogen it needs while providing the bacteria a sugar source. Nitrogen is a limiting factor for plant growth.
Nitrogen is found in all living systems as part of the makeup of biological compounds. Animals obtain the nitrogen they need by eating plants, or by eating other animals that have eaten plants.
Nitrogen gas in the atmosphere is converted by nitrogen-fixing bacteria into a form that plants can absorb, such as ammonium or nitrate. Plants take up these nitrogen compounds from the soil through their roots and incorporate them into proteins. When animals eat plants, they obtain nitrogen from plant proteins, continuing the cycle.
I don't think it is a gas when inside the plant, but most animals/plants need it.
because the nitrogen helps the plant grow
No
Nitrogen is required by plants and animals for protein synthesis

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.

mostly from food.
The animals obtain nitrogen through their foods in various forms to build proteins they need for their bodies. Protein synthesis is a continuous process in the plant and animal cells from some 20 odd types of amino acids, thousands of types of proteins are synthesized by the ribosomes in each organism.
