Methane is a significant part of the carbon cycle in ______ environments dominated by methanogens.

Question

Quizplus · Accepted Answer

Methane is primarily produced in anaerobic environments by methanogens, which are microorganisms that use carbon dioxide or organic compounds as their sole source of energy and carbon. Therefore, choice B, anaerobic environments, is the best answer. Autotrophic environments (A) refer to environments where organisms produce their own food, which is not directly related to methane production. Thermophilic (C) environments are those with high temperatures, which may or may not be anaerobic and can host methane-producing microorganisms. Oligotrophic (D) environments are low-nutrient environments, and again, there is no direct connection to methane production.
