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 some organisms, primarily bacteria and archaea, create organic molecules from inorganic substances (like hydrogen sulfide, H2S) using chemical energy, rather than light energy (photosynthesis). This is common in environments without sunlight, such as deep-sea vents.
Hint
The question specifies using 'chemical energy' from compounds like H2S, not light energy.
