Bacteria are required or needed in the nitrogen cycle because other living properties cannot use atmospheric nitrogen.
<h3>What is the nitrogen cycle?</h3>
The nitrogen cycle is the sequence of operations by which nitrogen and its mixtures are interconverted in the environment.
In living organisms, It considers nitrogen fixation and pollution.
As regards Nitrogen fixation is affected, just bacteria are competent to improve atmospheric nitrogen into structures usable by other living organisms.
In nitrogen fixation, the atomic nitrogen is converted into chemical forms functional by plants and convert atmospheric nitrogen into chemical forms functional by plants.
Therefore, option A is correct.
