Have you ever heard the word “biology” and wondered what it means? Let’s break it down! “Bio” means “life,” and “logy” means “the study of something.” So, biology is all about studying life.
There are many words that start with “bio.” For example, a biography is a story about someone’s life. Biodegradable means something that can be broken down by living things. A biologist is a person who studies life. Now, let’s dive into two more “bio” words: “biomass” and “biofuels.”
We know “bio” means life, but what about “mass”? Mass is the amount of matter in an object. So, when we say “biomass,” we’re talking about matter that comes from living things. All living things get their energy from the sun. Plants use a process called photosynthesis to capture sunlight. Biomass, like plants or animals, stores this energy. When we eat plants, our bodies break them down to release energy, which keeps us moving.
Some plants are grown for food, while others are grown to produce energy. Their biomass can be turned into fuel. For example, a tree can be chopped into wood chips, which can be used for mulch, playground surfaces, or even as biofuel to create heat. Since we can plant more trees, biomass is a renewable energy source, meaning we can keep making it.
Now, let’s talk about biofuels. “Fuel” is something that provides energy. So, “biofuel” is energy that comes from living things. Biomass is used to make biofuels. For instance, leftover vegetable oil from cooking can be turned into biofuel for cars. Ethanol is another biofuel made from grains like corn and wheat. Biodiesel and biojet fuel are other types of biofuels used in trucks and airplanes.
Fossil fuels, like coal and oil, come from ancient plants and animals buried in the earth for millions of years. They are non-renewable, meaning they can’t be replaced quickly. Biofuels, on the other hand, are renewable and considered cleaner for the environment.
Biofuels have some great benefits. They produce less pollution, help engines run longer, and reduce greenhouse gases that harm our planet. They also create jobs and make us less dependent on oil. However, biofuels can be expensive to produce, and growing the same crops repeatedly can harm the soil. Using land for energy crops might also lead to food shortages.
Despite these challenges, many people believe biofuels are a better choice than fossil fuels. With more research, biofuels might become the energy source of the future. Who knows, maybe one day you’ll drive a car powered by leftover vegetable oil!

**Biomass and Biofuels**
What do you think of when you hear the word “biology”? Do you know what it means? Let’s break the word down. “Bio” means “life,” and “logy” means “the study of something.” So if we put “bio” and “logy” together, we get “the study of life.”
Now, let’s look at some other words that begin with “bio.” A biography is the story of someone’s life. Biodegradable means something that can be broken down by living organisms. A biologist is a person who studies life and living organisms. Now that you know the meaning of “bio,” let’s learn about two more important “bio” words: “biomass” and “biofuels.”
Let’s break those words down, starting with biomass. We already know that “bio” means life. Now, let’s look at the word “mass.” Everything is made up of matter, including you. Mass is the amount of matter that objects are made of. When we add the word “bio” in front of “mass,” we’re talking about matter that comes from living things. All living things get their energy from the sun. Plants get it through a process called photosynthesis. Biomass, or the material from plants or animals, has stored sunlight or energy in them. This energy is released during a chemical reaction, like when people eat those plants. The food is then broken down in your stomach through digestion, releasing energy that feeds your body. That’s why it’s so important to eat good food—the better the food, the more energy it has to keep you moving.
Some plants are grown for us to eat, while others are grown specifically to produce energy. Their biomass, or leftovers, can be converted into fuel. A tree is a great example of biomass. If you have ever seen a tree taken down, you might have noticed that it is then put into a woodchipper, which turns it into tiny chips of wood and sawdust. Those chips can be used for mulch in a garden or for landscaping. They might be used to cover the floor of a playground or for barbecuing. Sawdust can be used as cat litter or to make particleboard. Wood chips are also used as biofuel and can be burned to create heat, which is a form of energy. A tree can be specifically grown and then burned for its energy, or it can be used for something else, like building a home or a fence. The leftover wood can then be burned for energy.
Because more plants and trees can be planted to replace those that have been used for energy, we call biomass a renewable energy source. This means it is a source of energy that we can create again and again. However, there is only so much land and water to regrow plants and trees, so it is necessary to find other sources that can be used for energy.
Crops used for fuel are called energy crops or power crops. They are grown on farms in very large quantities. One of the most popular power crops is corn. Like wood chips, dry shelled corn is also burned for energy. A gas called methane is produced when garbage in a landfill begins to rot. The methane gas can be used to heat homes and businesses. Interestingly, methane gas from cow manure can also be used to create energy.
Now, let’s take a look at our second “bio” word: biofuels. You are probably already familiar with the word “fuel.” Remember, “bio” means “life,” so “biofuel” refers to energy derived from living sources. Biomass is used to produce biofuels. An example of biofuel is the leftover vegetable oil that was used for making french fries. Corn was the biomass that created the vegetable oil, and the leftover oil becomes biofuel. That oil can be recycled and used as fuel in cars and trucks. In fact, one owner of four fast food restaurants engineered his car to run on used vegetable oil instead of gasoline.
Ethanol is another type of biofuel. It is often used in engines that usually burn gasoline. Ethanol is an alcohol made from the biomass of grains such as corn, barley, wheat, grass, sugarcane, and several other crops. Two other types of biofuels are biodiesel, which is used in large trucks and tractors, and biojet fuel, which is used in airplanes. These fuels are made by processing oil, fat, and sugar collected from plants or animals.
Besides biofuels, there’s another kind of fuel called fossil fuels. A fossil is an ancient organism, like a plant or animal, that has been preserved in rock. Fossil fuels are natural fuels formed in the earth from dead plants and animals that are millions of years old. We extract fossil fuels from the earth by digging, drilling, and mining. Fossil fuels like gas, coal, or oil are burned to produce heat or power. They are used in school buses, cars, and trucks, as well as in homes and businesses for heat and light. Fossil fuels are referred to as non-renewable energy sources, which means they cannot be replaced as quickly as they are used.
Biofuels differ from fossil fuels, even though materials made from plants and animals can be used to power things just like coal or gas. A significant difference is that many scientists believe biofuels are cleaner and better for the environment.
Let’s look at some advantages of using biofuels instead of fossil fuels for energy. They release less pollution into the air, engines can run longer on biofuels, and biofuels reduce greenhouse gases, which trap heat and cause harmful effects to our environment. Biofuels are renewable, meaning they can be replaced, like a tree that can be replanted. There are various sources that can be used for biofuels, and using them creates more jobs for people who need work. Additionally, biofuels help us become less dependent on oil.
While biofuels have some great advantages, there are also disadvantages. They can be expensive to produce, and the soil may lose nutrients when the same crop is grown year after year. Large amounts of water and fertilizer needed to grow these crops may lead to water pollution. If land is used to grow food for energy instead of for consumption, a food shortage might occur, potentially increasing food costs.
Many people still believe that biofuels are a better and cleaner option than fossil fuels, but due to the disadvantages, more research needs to be done on their use. Biofuels may become the energy source of the future. Maybe one day you’ll even own a car that runs on leftover vegetable oil!
