Explanation
Economic activities are classified into sectors based on the nature of value addition. The Primary Sector encompasses activities that involve the direct extraction, harvesting, or utilization of natural resources to produce raw materials.Analysis of Options
- Forestry: This involves the management and harvesting of forest resources. Since it relies directly on biological natural resources, it is a primary activity.
- Fishing: This entails the extraction of aquatic life from natural water bodies. It is a direct extractive activity, placing it in the primary sector.
- Mining and Quarrying: This involves the extraction of minerals and ores from the earth. Although often grouped under the "Industrial Sector" for GDP accounting in India, the fundamental nature of the activity is primary because it involves the extraction of natural resources rather than processing.
- Water Supply: This activity is typically categorized under "Electricity, Gas, and Water Supply", which falls within the Secondary Sector (Industry) or Utilities. It involves the collection, treatment, and distribution of water, distinguishing it from simple extraction.
Key Takeaway
The Primary Sector includes Agriculture, Forestry, Fishing, and Mining (extraction). The Secondary Sector includes Manufacturing, Construction, and Utilities (Electricity, Gas, Water Supply).
