Biofuel is basically fuel made from plants and animals. It's kind of like how we eat food to get energy, except we turn plants and animals into fuel to make machines run.
There are different types of biofuels, but the most popular are ethanol and biodiesel. Ethanol is made from corn or sugarcane, while biodiesel is made from oils like soybean or canola oil.
To make biofuel, we take the plants or animals and turn them into a liquid through a process called fermentation or distillation. Then, we can use this liquid to power cars, trucks, and other machines.
One cool thing about biofuels is that they're renewable. That means we can grow more plants and animals to make more fuel instead of using up non-renewable resources like oil. Plus, they usually produce less pollution than traditional fossil fuels like gasoline.
Overall, biofuels are a way to make energy from things that are good for the environment and can keep on being produced.
