Question
In which type of autotrophic nutrition do primitive prokaryotes utilize chemical energy from H2S and CO2 to synthesize carbohydrates?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The text describes chemosynthetic nutrition as the process where "primitive autotrophic prokaryotes used chemical (glycolytic) energy to make carbohydrates from H2S and CO2." This distinguishes it from photosynthesis, which uses light energy.
Hint
The question specifies the use of 'chemical energy' rather than light for carbohydrate synthesis.
