Which of the following is included in the primary sector?

The primary sector of the economy involves activities that directly use natural resources. These include farming, fishing, forestry, and mining. This sector is focused on extracting raw materials from the earth, which are then used to create goods or provide energy.

Let’s analyze the given options:

1. Manufacturing: This falls under the secondary sector, which deals with processing raw materials and producing finished goods. It is not part of the primary sector.
2. Tourism: Tourism belongs to the tertiary sector, as it provides services to people and does not involve natural resource extraction. Hence, it is not included in the primary sector.
3. Forestry: Forestry is the correct answer because it involves the harvesting of natural resources, such as timber, directly from forests. This is a classic example of a primary sector activity.
4. Communication: Communication is part of the tertiary sector, which includes service-based activities like providing internet, phone, and postal services. It is not part of the primary sector.

Final Answer:

The activity included in the primary sector is forestry.
