Every person on the world must have a supply of money, which is spent on expenses for living. And, of course, the usual way to earn money is to have a job. There is an uncountable amount of various professions. Some are only for men, some only for women, some for the young and some for the elderly. The entire economy could be divided into three spheres – primary, secondary and tertiary.

The primary sphere
The primary sphere means agriculture, fishing, hunting, wood cutting and mining. To sum up, the primary sphere is all the branches of economy, which use natural sources. The basic role of agriculture is to produce food and some materials for industry. The agriculture can be divided into plant and animal production. The animals are bred both for making food and for industrial production. Cows are kept all over the world; they are used for milk, meat, bones and skin.

The secondary sphere
The secondary sphere means industry. Factories produce various items, some are used for final usage), some for getting raw materials (oil towers, oil tankers, mine equipment), some for industry (equipment of factories, power stations) and some for agriculture (tractors, harvesters). There are many branches of industry, which cooperate with each other. One of the basic branches of industry is energetic, which produces electrical energy for the other branches.

The tertiary sphere
The tertiary sphere means services to people. It includes shops, travel agencies, restaurants, museums and galleries, offices, banks, church organisations, hospitals, schools, and also science. Altogether they are called non-productive economy. The number of people employed in services is different in different countries – the more developed country, the more people in services.
