Step-by-step explanation:
Economic activities that harvest or extract something from the Earth are categorized as Primary economic activities. These include sectors such as agriculture, forestry, fishing, and mining. The primary sector is fundamental for the economy because it provides the raw materials that can be processed and used in secondary activities.
