Describe three different levels of activity in which agricultural businesses engage.

    The primary sector is the segment of the economy that produces raw materials, such as agriculture, livestock, fishing and mineral extraction. It is a large sector in underdeveloped countries: in Africa, most countries have their populations living on subsistence agriculture.

    The secondary sector transforms primary goods into commodities and destines them for the commerce and services sector. The Secondary Sector of the economy is responsible for the transformation of goods and raw materials from the primary sector into commodities, which are transferred for trading in the tertiary sector.

    The tertiary sector is the field of the fastest growing capitalist economy with the most added value, characterized by the commercial inclusion of everything that does not encompass the other sectors. It is a complex and diverse arena where the focus is on interpersonal relationships.

Explanation:

    With the passing of the three industrial revolutions, the practice of agriculture today is based on advanced procedures, which denote a new feature for the geographical space, classified as a technical-scientific informational medium. Today, there are advanced techniques in soil management, machines and harvesters that do the work of dozens or even hundreds of workers at a faster rate, and advances in biotechnology development. This means that agricultural practices are increasingly subordinated to science and knowledge production.

    But it is important to point out that there are not only modern techniques about the countryside. We can say that different types of advances coexist in rural space, although large and more developed properties occupy most of the space. There are modern farming systems at the same time as there are traditional forms of cultivation such as organic, shifting and gardening.

    The importance of agriculture is therefore unquestionable because it is from it that the food and primary products used by industries, commerce and the service sector are produced, becoming the basis for the maintenance of the world economy.
