Final answer:
Transformed resources are resources that have been converted during production, turning natural raw materials into finished products through secondary sector activities such as manufacturing.
Step-by-step explanation:
Transformed resources refer to c. Resources converted during production. During the production process, raw materials and other inputs are transformed into finished goods or services. These resources start as natural resources, such as the ingredients used in making pizza or the crops grown by farmers. They are processed and manufactured, which is considered a secondary economic activity, to create products that can be used to produce other goods and services. For instance, wheat may be processed into flour and then used to bake bread, or iron ore may be smelted and turned into steel for construction. Economists recognize that resources must undergo transformation through manufacturing or secondary sector activities to become valuable finished products.
