• C. Nitrobacter
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

Chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter by the use of energy from the chemical reaction between the inorganic molecules (e.g. hydrogen gas,hydrogen sulfide) or methane, rather than sunlight, as in photosynthesis e.g., Nitrobacter and sulphur bacteria.
