The economy is divided into four main sectors: primary, secondary, tertiary, and quaternary. Each sector has a distinct role, from resource extraction to innovation. Understanding this classification helps explain the structure and function of an economy.
This section establishes the foundational framework of economic activity by clearly defining and differentiating the four main sectors.
Natural resources: Raw materials obtained directly from nature that are used as inputs for other sectors.
Agriculture: Cultivation of crops as a primary economic activity.
Fishing: Harvesting aquatic animals and plants for consumption or sale.
Forestry: The management and harvesting of forests for timber and other products.
