Hydrocarbon - GCSE Biology Definition

A hydrocarbon is a chemical compound that is made up only of carbon and hydrogen atoms. These compounds are the main components of fossil fuels like oil, coal, and natural gas, which we use for energy. Hydrocarbons can be found in different forms, such as gases, liquids, or solids. In the context of biology, hydrocarbons are important because they can be broken down by living organisms to release energy. This energy is crucial for carrying out various life processes. Understanding hydrocarbons also helps us learn about environmental issues, like pollution and climate change, since burning fossil fuels releases carbon dioxide, a greenhouse gas.
