Final answer:
Methane is produced by anaerobic decomposition in landfills by methanogens using CO2 as their final electron acceptor. Landfills contribute significantly to methane emissions. Landfills contribute significantly to methane emissions as the waste undergoes anaerobic decomposition when buried under layers of trash and soil.
Step-by-step explanation:
Methane is produced by anaerobic decomposition in landfills. Methanogens, which are a group of archaea, use CO2 as their final electron acceptor during anaerobic respiration, producing CH4 (methane). Landfills contribute significantly to methane emissions as the waste undergoes anaerobic decomposition when buried under layers of trash and soil.
