Chapter 27, Problem 4MCQ
Summary Introduction
Introduction:
Methane, a potent greenhouse gas, is constantly produced by methanogenic bacteria in the benthic zone. Such benthic zones are located at the lowest level of oceans or lakes and have less concentration of oxygen. Methane-producing bacteria, a part of anaerobic benthic population, also play a crucial role in sewage treatment.
