The Methanogens, Producers of Methane Gas, Require Environments That

Question

The methanogens, producers of methane gas, require environments that
A)have sunlight.
B)are very acidic.
C)have abundant oxygen and CO2.
D)are extremely cold.
E)are anaerobic with hydrogen gas and CO2.

Accepted Answer

Methanogens are organisms that produce methane gas through anaerobic respiration, which means they require an environment that lacks oxygen. They also require a source of hydrogen gas as well as carbon dioxide and other nutrients. Therefore, option E is the best choice as it describes an anaerobic environment with the necessary gases for methanogens to thrive.
