Why do plants animals and other organisms need nitrogen?
Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms.
Why is nitrogen needed by living organisms?
Amino acids, DNA and RNA have nitrogen element. Therefore, all living cells require nitrogen. Also, nitrogen gas is inert in nature. As the major component of the atmospheric gases is nitrogen gas, it helps in making the environment of the Earth inert, preventing chemical reactions like fire, etc.
Why is nitrogen needed for plants?
Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes. Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.
Why is nitrogen important US?
Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.
Why do plants and animals need nitrogen in form of nitrates and nitrites?
Answer: Due to the nitrogen cycle, nitrates and nitrites are released into the soil which helps in enriching the soil with nutrients needed for cultivation. As plants use nitrogen for their biochemical processes, animals obtain the nitrogen and nitrogen compounds from plants.
