Nitrifying bacteria are the examples of___________?
Correct answer: B. Chemosynthetic bacteria
- A. Hetrotrophic bacteria
- B. Chemosynthetic bacteria
- C. Saprophytic bacteria
- D. Parasitic bacteria
Explanation
Nitrifying bacteria obtain energy by oxidizing inorganic nitrogen compounds such as ammonia or nitrite, so they are chemosynthetic, specifically chemoautotrophic, bacteria. The likely alternative is heterotrophic bacteria, but heterotrophs obtain organic nutrients rather than energy from inorganic chemical oxidation.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
