Grinding wheat into flour is an example of which type of economic activity?

Grinding wheat into flour represents secondary economic activity because it involves the processing of raw materials into finished goods. In this case, the raw material is wheat, which is transformed into flour through a manufacturing process. Secondary activities focus on the transformation of natural resources into products that can be used by consumers or businesses, thus adding value to the raw materials.

Primary economic activities, in contrast, are concerned with the extraction of natural resources, such as agriculture, mining, and fishing. These activities do not involve the processing of raw materials into finished products. Tertiary economic activities involve the provision of services rather than goods, such as retail and hospitality. Quaternary activities are based on knowledge and information, including research and development or financial services, which again do not pertain to the physical processing of goods like flour.
