The economy is divided into three main sectors: the primary, secondary, and tertiary sectors. The primary sector involves the extraction of natural resources, such as farming, fishing, and mining. This sector provides the raw materials needed for other industries. The secondary sector focuses on manufacturing and construction, where raw materials are transformed into finished products. Finally, the tertiary sector encompasses services, including healthcare, education, and retail. Together, these sectors illustrate how different parts of the economy work together to create goods and services that meet people's needs.
