Hint: A fossil is a natural extracted fuel, for example, the anaerobic decompression of buried dead animals, while biofuel is any biomass fuel, plant or algae, or animal waste. Since these materials can quickly be replenished, biofuels are considered a renewable energy source.

Complete answer: Although fossil fuels and biofuels have many similarities, there are also important differences, including the following:
CharacteristicsBiofuelsFossil fuel
MeaningGreen fuel or biofuel is a type of distilled fuel that is environmentally safe to obtain from plants and animal content that gives the name green fuel behind them. To preserve our environmental resources, biofuel is synthesized.Fossil fuel is an all-around term for buried fuel geological deposits created from decayed plants and animals transformed by exposure to heat and pressure to crude oil, coal, natural gas, or heavy oils.
TypeBiofuels are renewable.Fossil fuels are non-renewable.
SourceThe majority of biofuels come from contemporary grain or from modern plants' organic residue.Although for millions of years species that are made of fossil fuels have been extinct.
ToxicityBiomass is usually non-toxic.The byproducts of the combustion of fossil fuels are toxic gases and particles that cause lung irritation or harm.
State of industryBiofuels are seeing and becoming increasingly popular in an environmentally friendly way.The use of fossil fuels is currently controversial, and many countries are currently seeking to get away from fossil fuels.
PollutionFewer pollutants are released.Most contaminants are released
Examples:Biodiesel, bioethanol, etc.Coal, natural gas, etc.

Biofuels are produced from plants that have been converted to fluid fuel and other organic matter. Ethanol and biodiesel are biofuel types. Ethanol is normally made from cellulose ethanol, excluding grains. Made of vegetable oil, animal fat, and cooking grease, organic diesel is created. Ethanol is developed to substitute for petrol, while biodiesel is employed for diesel substitution. Biofuels are typically non-toxic and can reduce the reliance of a nation on imports of foreign fossil fuels. On the other hand, biofuels have insufficient energy to substitute fossil fuels entirely. The use of biofuels also generates competition between food crops and fuel crops. In addition, it emits about the same amount of carbon dioxide as fossil fuels in many instances.

Note: Gasohol is another form of green fuel as a renewable and non-renewable fuel mix. Gasohol is typically a mixture of 90% petrol with 10% ethanol. Related are fossil fuels and biofuels, as both are made from living material after they have been burnt and both emit carbon dioxide.
