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 A is the correct answer.
Detailed Explanation
Chemosynthesis is a process by which certain organisms, primarily bacteria and archaea, produce organic compounds, usually carbohydrates, using the oxidation of inorganic chemical compounds (like hydrogen sulfide) as a source of energy, rather than sunlight. This is characteristic of primitive autotrophic prokaryotes in environments without light.
Hint
The question specifies 'chemical (glycolytic) energy' and 'H2S and CO2' rather than sunlight. Consider the source of energy.
