Question
According to the chemosynthesis equation section, which of the following can serve as a chemical source of energy for chemosynthesis?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 5, under 'Reactants', states: 'A chemical source of energy such as hydrogen gas, hydrogen sulphide or ferrous iron'. Carbondioxide and methane are carbon sources, not energy sources in this context.
Hint
Distinguish between the 'carbon-containing inorganic compound' and the 'chemical source of energy' in the reactants section.
