Understanding Azotobacter

Azotobacter is a genus of nitrogen-fixing bacteria that plays a vital role in the nitrogen cycle. These bacteria are important in agriculture as they convert atmospheric nitrogen into a form that plants can utilize.

Options Analysis

1. Autotrophic: These organisms produce their own food using light or chemical energy. Azotobacter can be classified as autotrophic because it can utilize atmospheric nitrogen for growth.

2. Saprotrophic: These organisms obtain nutrients by decomposing organic matter. This does not describe Azotobacter.

3. Parasitic: Parasitic organisms rely on living hosts for nutrients. Azotobacter does not fall into this category.

4. Mutualistic: Mutualistic organisms engage in a symbiotic relationship where both parties benefit. While Azotobacter can have beneficial relationships with plants, it primarily acts independently.

Conclusion

Azotobacter is best described as Autotrophic bacteria because of its ability to fix atmospheric nitrogen and contribute to nutrient cycling.
