The document summarizes the three sectors of the economy: - The primary sector involves extracting raw materials through activities like agriculture, forestry, fishing and mining. - The secondary sector processes and manufactures raw materials into finished products through industries. It produces intermediate products used by other industries and consumer products sold directly to consumers. - The tertiary sector is the service sector and includes areas like health, education, transportation, tourism and more that sell products and provide services to consumers.

7. The secondary sector uses raw materials to produce manufactured products.
There are different types of products: some industries produce intermediate
products and other industries produce consumer products.
3. THE SECONDARY SECTOR
Intermediate products
These are products that are used
by other industries to make other
products.
Steel is an intermediate product.
Consumer products
