The first stage of production is also known as an extractive industry? Why?

The first stage of production, also known as an extractive industry, is called so because it involves the extraction of raw materials from the earth. This can include mining, drilling, logging, and other processes that extract natural resources such as minerals, oil, gas, timber, and water. These industries rely on harvesting or extracting resources directly from the environment, rather than manufacturing or processing already existing materials. Extractive industries are essential for providing the raw materials necessary for manufacturing and other industries, making them a crucial part of the overall production process.
