Answer 2

"Methanogens are the odd one out" and they are not heterotrophic.

Explanation:

The methanogens bacteria are methane-producing bacteria. The "Methane" is produced in the "rumen and hindguts".

Among livestock, methane formation is greatest in ruminants, as "methanogens are enough capable to produce the methane" during the usual process of food digestion.

They stay alive in extreme heat and cold. They are strict anaerobes producing methane in the "absence of oxygen molecules".
