... quite sure it refers to the industries (as well)
PRIMARY - agriculture, mining, fishing ect
SECONDARY - manufacturing and processing ect
TERTIARY - service sector
These are important so make sure you are aware of the differences between them!
EDIT: "from my updated notes thanks to waldo777's comment above"
Organisations:
- Can achieve things that individuals cannot alone (therefore comprise of 2 or more people)
- Can produce goods and services more efficiently due to their large number of staff and ability to specialise (done at a reduced cost)
- Provide an important source of employment
- Have complex management structures due to their size and complexity (formal or informal)
- Have a purpose
There are three main industries:
- Primary (mining, agriculture, fishing, forestry)
- Secondary (manufacturing, processing, construction)
- Tertiary
- Quaternary (service sector, IT, finance)
- Quinary (hospitality, health, domestic services – paid and unpaid)
