Primary Industries involve the extraction of raw materials directly from the earth. Example: Agriculture (growing crops and raising livestock) or fishing. Challenges: Highly dependent on weather conditions, vulnerable to price fluctuations, often low profit margins, can have environmental impacts (e.g., deforestation, pollution).
Secondary Industries involve the processing of raw materials into finished goods. Example: Manufacturing cars or textiles. Challenges: High capital investment required, susceptible to competition from countries with lower labour costs, potential for pollution, requires skilled labour.
Tertiary Industries provide services to consumers and businesses. Example: Retail, banking, healthcare, tourism. Challenges: Can be affected by economic downturns (reduced consumer spending), requires a skilled and customer-focused workforce, often involves high levels of competition.
Quaternary Industries involve intellectual activities such as research and development, information technology, and consultancy. Example: Software development, scientific research, financial analysis. Challenges: Requires highly skilled and educated workforce, vulnerable to rapid technological changes, often involves significant investment in research and development.
