With vivid example from Tanzania explain how commerce completes production process

Commerce is a fundamental part of the productive economic process, through which the goods and services that were produced in an economy are placed on the market. Thus, it is part of the third sector of the economy, capitalizing production and supplying the public with the goods and services it needs for its daily development.

Thus, for example, the Tanzanian economy is made up of 80% agricultural production, which makes up the primary sector of the economy. This country lacks a developed industrial structure, so its secondary sector is very short. Now, the agricultural products that are produced in the country are marketed both in the domestic market and through exports, with which the tertiary sector of the Tanzanian economy is based in turn on the nation's primary production.
