Which sector is responsible for transforming and assembling raw materials into products?

The secondary sector is responsible for transforming and assembling raw materials into finished goods. This sector encompasses manufacturing and construction processes where raw materials, sourced from the primary sector, are processed into products that can be sold to consumers or other businesses. For example, in the secondary sector, iron ore might be processed in a steel mill to create steel, which can then be used in the construction of buildings or vehicles.

In contrast, the primary sector focuses on the extraction and harvesting of natural resources, such as agriculture, forestry, and mining, with raw materials being gathered but not yet transformed into finished products. The tertiary sector is concerned with providing services rather than goods, including retail, healthcare, and education, which do not involve the physical transformation of materials. The quaternary sector covers knowledge-based activities and services, such as research and development, which again differ from the transformational processes characteristic of the secondary sector.
