Question
In this type of autotrophic nutrition, the primitive autotrophic prokaryotes used chemical (glycolytic) energy to make carbohydrates from H2S and CO2.
Correct Answer
Option B is the correct answer.
Detailed Explanation
Chemosynthesis is a process by which certain organisms, often primitive prokaryotes, obtain energy by oxidizing inorganic substances (like hydrogen sulfide, H2S) rather than using sunlight, to synthesize organic compounds from carbon dioxide. Photosynthesis uses light energy.
Hint
The question explicitly mentions 'chemical (glycolytic) energy' and 'H2S and CO2' rather than light.
