Question
In this type of autotrophic nutrition, the primitive autotrophic prokaryotes used chemical (glycolytic) energy to make carbohydrates from H 2 S and CO 2
Correct Answer
Option C is the correct answer.
Detailed Explanation
Chemosynthesis is a process used by some organisms (chemoautotrophs), primarily prokaryotes, to produce organic compounds by oxidizing inorganic substances (like hydrogen sulfide, H2S) as an energy source, rather than using sunlight as in photosynthesis. Heterotrophic and holozoic describe modes of nutrition where organisms consume other organisms or organic matter.
Hint
The key here is the use of 'chemical energy' and inorganic compounds to produce food, distinguishing it from light-based methods.
