How is the tertiary sector different from other sectors? Illustrate with a few examples.

The activities that help in the development of the primary and secondary sectors comprise the tertiary sector. These activities, by themselves, do not produce any goods but they are an aid or a support for the production process. For example, goods that are produced in the primary or secondary sector would need to be transported by trucks or trains and then sold in wholesale and retail shops. Here transportation forms the tertiary sector. Tertiary sector or service sector also includes some essential services that may not directly help in the production of goods. For example, we require teachers, doctors, and those who provide personal services such as washermen, barbers, cobblers, lawyers etc. They are different from primary sector that produces goods using the natural resources and manufacturing sector or secondary sector that involves production of goods using the raw material produced by primary sector.
