Sugar, carbon dioxide and water are all chemicals that are held together by what we call chemical bonds or forces that hold the chemicals together. For example, all sugars are composed of carbon, oxygen and hydrogen atoms that are held together by chemical bonds. These atoms don't just stick together automatically.
How do plants use energy?
Plants use energy from the sun to make sugar and oxygen from carbon dioxide and water. We, along with other animals, digest that sugar to release energy, so we can do work. Sugar is digested; in other words it's broken down, into carbon dioxide and water, which, in turn, is used by plants to make more sugar.

When a chemical is broken down, we call it an exothermic reaction?
When chemicals are broken down, we refer to it as an exothermic reaction as energy is released from the reaction and can be used to do work. When a larger chemical is made from smaller building blocks, we call this an endothermic reaction as energy is required to build the bigger molecule from the smaller components.
What is Chemical Energy?
Chemical energy is defined as the energy that is stored in the bonds of chemical compounds such as atoms and molecules. This energy gets released whenever a chemical reaction is taking place. Generally, when the chemical energy is released from the substance, it tends to transform into an entirely new substance. The stored chemical energy is released whenever a chemical reaction takes place. Heat is produced often in the form of a by-product of that chemical reaction. This is known as an exothermic reaction. Chemical energy is one of the most used kinds of energies in the world because it is crucial for the existence of not only humans but also all living beings and the natural world. In this article, we will study what is chemical energy, the chemical energy formula, the chemical energy meaning and the chemical energy examples.
How is chemical energy released?
Chemical energy is released when a chemical reaction takes place, generally in the form of heat. These reactions are known as exothermic reactions. Reactions which need a heat input for proceeding may even store some of this energy in the form of chemical energy in the newly formed bonds. The chemical energy present in food gets converted by the body into heat and mechanical energy. The chemical energy present in coal gets converted into electrical energy at a power station. The chemical energy present in the battery is also able to supply electrical power with the help of the process of electrolysis.
What is the energy in food?
The food that we eat daily consists of stored chemical energy . When the bonds between the atoms in the food items tend to break or loosen up, a chemical reaction tends to take place and entirely newer compounds are formed. The energy that is produced from this chemical reaction keeps our body warm, helps us in the day to day movements and also contributes to our growth. However, different kinds of foods tend to store different amounts of energy in different forms. Hence, we can say that the food we eat daily contains stored chemical energy. This chemical energy then gets converted to different forms of energy such as mechanical energy which helps us in the day to day movement.
What are the atoms that make up sugar?
Consider for example that all sugars contain carbon, hydrogen and oxygen atoms that are held together by several chemical bonds. However, these atoms do not get connected automatically, and some kind of energy is needed to make them stay attached.

Chemical energy, found in many energy-rich molecules on Earth, undergoes one of many reactions to become kinetic energy. For example, oxygen is the most common chemical energy-containing molecule. When ignited, oxygen mixed with hydrocarbons such as fossil fuels, wood, and other plant material or biofuels undergoes chemical transformation to release energy.
What Chemical Reactions Release Energy?
When chemical reactions release energy, they’re called exothermic reactions . During exothermic reactions, chemical bonds release more energy than they use to create their end products. As a result, temperature decreases in endothermic reactions.
