Which industry processes output from the primary sector into products?

The manufacturing industry is the correct answer as it specifically refers to the sector that transforms raw materials and outputs from the primary sector into finished goods and products. This process typically involves various techniques and operations that convert basic materials, such as metals, plastics, or agricultural products, into consumable items or components for other products.

The primary sector includes industries that extract natural resources, such as agriculture, forestry, fishing, and mining. The manufacturing sector then takes the outputs of these industries and adds value through processes such as assembly, machining, or chemical fabrication, which culminates in a final product that can be sold to consumers or other businesses.

In contrast, the tertiary sector focuses on providing services rather than tangible goods. The construction sector is a subset of the broader manufacturing category, primarily dealing with the building of infrastructure and facilities, not the processing of raw materials into products. The service sector encompasses businesses that provide services such as retail, healthcare, education, and hospitality but again does not engage in manufacturing. Therefore, the manufacturing industry is the sector explicitly responsible for processing primary sector outputs into market-ready products.
