Primary Sector vs Secondary Sector:
Primary Sector: Economic activities that involve direct use of natural resources are called primary sector activities. Production depends mainly on natural factors like rainfall, climate, and soil. Since it forms the base for all other sectors, it is called "primary."
Examples: Agriculture, dairy farming, fishing, forestry, mining.
Secondary Sector: Economic activities in which natural products are transformed into other forms through manufacturing or processing are called secondary sector activities. The product is not directly obtained from nature but has to be made through an industrial process. It is also called the industrial sector.
Examples: Cotton fibre spun into yarn and woven into cloth; sugarcane converted into sugar; clay converted into bricks and bricks used to make buildings.
Key Difference: The primary sector extracts or produces raw materials directly from nature, while the secondary sector uses those raw materials to manufacture finished goods.
