Primary sector : Raw materials :: Tertiary sector : ?

The primary sector involves the extraction and production of raw materials, like farming, mining, and fishing. In contrast, the tertiary sector focuses on providing services rather than goods. This means that while the primary sector gathers resources, the tertiary sector offers support and help to people, such as healthcare, education, and retail. For example, a hospital is part of the tertiary sector because it provides medical services to people instead of producing physical products. Therefore, we can say that just as raw materials come from the primary sector, services come from the tertiary sector.
