The nitrogen cycle relies on bacteria to convert atmospheric nitrogen gas into a form that plants can absorb and utilize. This process involves various types of bacteria converting nitrogen gas into first ammonium, then into nitrites, and finally into nitrates. Without the presence of these bacteria, nitrogen would remain in its unusable form, ultimately disrupting the balance of nutrients necessary for plant growth and overall ecosystem health. Thus, bacteria play a crucial role in facilitating the conversion of nitrogen in the environment, allowing for its cycling and availability to sustain life.
