Question
Which type of autotrophic nutrition involves primitive autotrophic prokaryotes utilizing chemical (glycolytic) energy to synthesize carbohydrates from H₂S and CO₂?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Chemosynthesis is the process by which certain organisms obtain energy by oxidizing inorganic substances (like H₂S) rather than by photosynthesis, typically found in primitive prokaryotes or organisms living in extreme environments like deep-sea vents.
Hint
The key distinguishing factor is the use of 'chemical energy' from inorganic compounds, as opposed to light energy.
