*Biomass* is a kind of energy. It comes from plants and animals. People use wood, food waste, and animal waste to make energy. This energy can make heat and electricity. It helps people cook food, warm their homes, and turn on lights. Biomass is good for the Earth. It is clean and natural. When people use food or wood waste, they don’t throw it away. They use it again. This helps reduce trash. Also, we can grow more plants, so biomass does not run out. That’s why it is called *renewable energy*. In some places, people burn wood to cook. In big cities, factories use food or animal waste to make gas. This gas gives electricity to houses and schools. Biomass does not pollute the air as much as oil or coal. It is better for the environment. It helps people and the planet. Many countries are starting to use more biomass. It is safe, clean, and smart. In the future, more people may use it to save energy and help nature.
