Which is a role of helpful bacteria?

removing nutrients from soil

producing oxygen

healing sick animals

preventing tooth decay

Answers

Answer 1

Answer:

Producing oxygen

Explanation:

Bacteria actually add to nutrients in soil because they decompose the organic matter such as dead bodies and such. I do not know if bacteria heal sick animals or if they prevent tooth decay rather I am sure they cause both of those.

Therefore, most plausible answer is producing oxygen because there are bacterias like cyanobacteria, or blue-green algae who go through photosynthesis and produce oxygen which is beneficial for all living beings.

Answer 2

Helpful bacteria helps in producing oxygen for carbon di oxide in th environment. Therefore, option (B) is correct.

What are helpful bacteria?

Probiotics are live bacteria that are beneficial to our health, that help maintain a healthy balance of good and bad bacteria in our intestinal tract, that contribute to the digestion of food and that alleviate digestive issues such as bloating and diarrhea. Lactobacilli and Bifidobacterium are two types of bacteria that are considered to be examples of probiotics.

Through the process of photosynthesis, extremely minute bacteria known as prochlorococcus are busily converting carbon dioxide into the oxygen that we breathe.
