What is the role of nitrogen-fixing bacteria in the nitrogen cycle?

• They convert nitrogen gas into ammonium

• They decompose dead plants

• They release oxygen into the atmosphere

• They produce carbon dioxide

Answer explanation

Nitrogen-fixing bacteria play a crucial role in the nitrogen cycle by converting nitrogen gas from the atmosphere into ammonia, which can be used by plants. This process is essential for making nitrogen accessible in the ecosystem.
