Question
In which type of autotrophic nutrition do primitive autotrophic prokaryotes use chemical energy (glycolytic) to synthesize carbohydrates from H₂S and CO₂?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Chemosynthesis is a process by which some organisms, particularly bacteria and archaea, produce organic compounds using chemical energy from the oxidation of inorganic substances, such as hydrogen sulfide (H₂S), instead of light energy.
Hint
The question explicitly mentions 'chemical (glycolytic) energy' for carbohydrate synthesis.
