Labour and entrepreneur are examples of "factors of production".
Factors of production are the resources used in the production of goods and services. The four main factors of production are land, labour, capital, and entrepreneurship.
Labour refers to the physical and mental effort of people involved in the production process, while entrepreneurship refers to the ability to organize, manage, and take risks in starting and operating a business venture.
In other words, labour and entrepreneurship are the human resources required for production. They play an important role in generating income and creating economic growth.
