Chemoautotrophs are cells that break down inorganic molecules to supply energy for the cell, and use carbon dioxide as a carbon source. Chemoautotrophs include prokaryotes that break down hydrogen sulfide (H 2 S the “rotten egg” smelling gas), and ammonia (NH 4 ). Nitrosomonas , a species of soil bacterium, oxidizes NH 4 + to nitrite (NO 2 - ). This reaction releases energy that the bacteria use. Many chemoautotrophs also live in extreme environments such as deep sea vents.
