Industries are classified as

Industries are classified into different types based on their function and output. The most common classification of industries is into primary, manufacturing (also known as secondary), and tertiary industries. Primary industries are involved in the extraction and production of raw materials such as mining, farming, and fishing. These industries are the basis of all other industries because they provide the raw materials needed for production. Manufacturing or secondary industries involve the transformation of raw materials into finished products such as cars, textiles, and electronics. These industries add value to the raw materials obtained from the primary industries. Tertiary industries are also known as service industries and include businesses such as banking, transportation, and healthcare. These industries provide services to people and other industries. Other classifications of industries can include cocoa processing, furniture making, and food processing, but these are usually considered as subcategories of manufacturing or primary industries.
