Correct Option
The correct option is 2 and 3 only.
Explanation
An economy is structurally divided into three main sectors: Primary (extraction of natural resources), Secondary (manufacturing and processing), and Tertiary (services). These sectors are highly interdependent, creating a symbiotic relationship where the output of one often serves as the input or support system for another.
Statement-wise Analysis
- Statement 1 is Incorrect: The secondary sector transforms natural products into other forms through manufacturing. It is heavily dependent on the primary sector for raw materials. For example, the textile industry relies on cotton (agriculture), and the steel industry relies on iron ore (mining).
- Statement 2 is Correct: The primary sector, particularly modern agriculture, relies on the secondary sector for crucial inputs. Manufactured goods such as chemical fertilisers, pesticides, tractors, and harvesting machinery are essential for increasing productivity in the primary sector.
- Statement 3 is Correct: The tertiary sector produces services rather than goods. It provides essential support systems such as transportation, banking, insurance, communication, and storage, which facilitate the production and distribution processes of both the primary and secondary sectors.
Key Takeaway
Sectoral Interdependence: No economic sector functions in isolation; the primary sector provides raw materials, the secondary sector produces industrial inputs and consumer goods, and the tertiary sector provides the logistical and financial infrastructure required for the entire economy to operate.
