What are fuels that remains from plants and animals?

Fuels that remain from plants and animals are known as fossil fuels, which include coal, oil, and natural gas. These fuels are formed over millions of years from the decomposed organic matter of ancient plants and animals subjected to heat and pressure beneath the Earth’s surface. Additionally, biomass, which consists of organic materials like wood and crop residues, can also be considered a fuel derived from plants. These energy sources are significant for powering industries, transportation, and electricity generation.
