Most organisms (including you) break down organic compounds to obtain energy and nutritional building blocks. In contrast, chemolithotrophs are prokaryotes that obtain energy through the oxidation of inorganic compounds. Which of the following inorganic molecules would these microbes also need to build macromolecules for new cell material? Choose one:a. O2b. H2c. CO2d. N2e. H2O

Answer: Carbon dioxide

Explanation:

The chemolithophs are the prokaryotes which uses inorganic matter in order to make organic materials for the other processes.

These organism get energy by the oxidation of the inorganic compounds. The organism such as human beings breaks down the organic compounds in order to get energy and nutritional building block.

The macro molecule used by the organism is carbon dioxide.
