Chemoautotroph Bacteria

Microorganisms that obtain energy through chemical reactions using inorganic molecules, supporting themselves without needing sunlight or organic nutrients.

Carbon Dioxide

A colorless, odorless gas produced by burning carbon and organic compounds and by respiration, absorbed by plants in photosynthesis.

Organic Compound

A chemical compound that contains carbon atoms bonded to hydrogen atoms and often other elements, found in all living organisms.
