Question

explain the main step of nitrogen cycle with the help of diagram

​

Answer 1

Answer:

Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction

Answer 2

Answer:

We are generally under the impression that we only need oxygen to live. Well, you couldn’t be more wrong! There is a laundry list of elements that animals need for survival. One such element is Nitrogen. But we can’t just get nitrogen from the air. It needs to be converted to nitrates, via a process called nitrogen cycle. So let us learn more about this fascinating concept.

The air we breathe contains 78% nitrogen, 21% oxygen and remaining are other trace gases. The nitrogen component of air is inert. So this means plants and animals cannot use it directly. To be able to use nitrogen, plants convert atmospheric nitrogen to nitrates, nitrites and ammonia compounds by a process called the nitrogen cycle. Animals derive their nitrogen requirements from plants.

Explanation:

What are the steps involved in the nitrogen cycle?

Nitrogen cycle consists of four main steps namely:

Nitrogen Fixation

Ammonification/ Decay

Nitrification

De-nitrification

It is important to note that microorganisms play an important role in each of these steps.
