Methane is most common hydrocarbon.where is methane produced?

Methane is primarily produced in several natural and anthropogenic sources. Naturally, it is generated in wetlands, during the digestion of organic matter by microorganisms, and from geological sources such as natural gas deposits. Anthropogenic sources include livestock digestion (enteric fermentation), landfills, and the extraction and processing of fossil fuels. Overall, it plays a significant role in the global carbon cycle and contributes to greenhouse gas emissions.
