Fuels such as ethanol or methanol created from fermentation of plants are called what?

Explanation:
Biofuels are fuels produced from biomass—organic material from plants or plant wastes. Ethanol is a classic example, made by fermenting sugars in crops like sugar cane or corn, and methanol can also be produced from plant matter through certain processes. Because they come from renewable plant sources rather than fossil fuels, these fuels are grouped as biofuels. They are used as alternatives to petrol and diesel, often blended with them to reduce dependence on fossil fuels and cut greenhouse gas emissions, though sustainable production and land-use impacts need careful management.
