Answer 1

Bacteria are a necessary part of the nitrogen cycle because other living things cannot use atmospheric nitrogen, which is option A.

What is nitrogen cycle?

Nitrogen cycle is the natural circulation of nitrogen between the biosphere and atmosphere.

In the nitrogen cycle, atmospheric nitrogen (N2) is converted to nitrogen oxides by lightning and deposited in the soil by rain.

This is then assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

Therefore, bacteria are a necessary part of the nitrogen cycle because other living things cannot use atmospheric nitrogen.
