Answer:
e. All of the choices are correct.
Explanation:
Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.
Many nitrogen-fixing bacteria like Rhizobium, Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.
So bacteria like <em>Pseudomonas putida</em> decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.
