Question

What are the 4 types of bacteria involved in the nitrogen cycle?

Answer 1

The four types of bacteria involved in the nitrogen cycle are nitrogen-fixing, nitrifying, denitrifying, and decomposing bacteria.

Step-by-step explanation:

The four types of bacteria involved in the nitrogen cycle are:

1. Nitrogen-fixing bacteria: These bacteria convert nitrogen gas in the atmosphere into a form that plants can use, such as nitrates.
2. Nitrifying bacteria: They convert ammonia into nitrites and then into nitrates.
3. Denitrifying bacteria: They convert nitrates back into nitrogen gas, completing the cycle.
4. Decomposing bacteria: These bacteria break down organic matter, releasing ammonia into the soil.

All four types of bacteria play crucial roles in the nitrogen cycle, helping to make nitrogen available to plants and maintain a balanced ecosystem.
