Answer:
In the soil, some bacteria convert nitrogen to a form that can be used by plants.
Step-by-step explanation:
The types of products that are utilized by plants are known as inorganic products. The soil most typically contains organic material and humus but it can not be directly utilized by plants. So, decomposers and prokaryotes convert this organic product into an inorganic one.
According to the context of this question, nitrogen fixation is a process through which some bacterial species significantly convert the organic form of nitrogen (N2) into an inorganic one like (NH4+) which is easily consumed by plants for their growth and development. This is the importance of bacterial species in the environment.
