The primary sector is the “farm” of the economy – it gathers raw materials straight from nature. Think of it as the garden where you grow the food that feeds everyone.
Example businesses: GreenFields Farm, DeepSea Fisheries, RockSolid Mining Ltd.
The secondary sector is like the factory that turns raw ingredients into finished products. It’s all about manufacturing and construction.
Example businesses: AutoMakers Inc., BuildRight Construction, FreshFoods Processing
The tertiary sector is the “service” side of the economy – it’s all about providing services to consumers and other businesses. Think of it as the shop that sells the finished goods and offers extra help.
Example businesses: ShopSmart Retail, SecureLife Insurance, BrightFuture School, SunnyStay Hotels
The quaternary sector is the “knowledge” side of the economy. It deals with information, technology, and research. Imagine it as the brain that keeps the economy smart and innovative.
Example businesses: CodeCrafters Ltd., FutureTech R&D, Insight Consulting, StreamWave Media
