Correct Option
The correct option is 1, 2, 3 and 4.
Explanation
Natural vegetation in India is classified into various types based primarily on rainfall, temperature, and altitude. Specific tree species are characteristic of these distinct climatic zones, adapting to the moisture and thermal conditions of their environment.
Statement-wise Analysis:
- Pair 1 is correctly matched: Mahogany is a commercially important tree species found in Tropical Evergreen Forests. These forests thrive in areas with heavy rainfall (over 200 cm) and high humidity, such as the Western Ghats and the North-Eastern hills. Other examples include Ebony, Rosewood, Rubber, and Cinchona.
- Pair 2 is correctly matched: Teak is the most dominant species of Tropical Moist Deciduous Forests. These forests are found in regions recording rainfall between 100 cm and 200 cm. Other common trees include Sal, Shisham, Hurra, Mahua, Amla, Semul, Kusum, and Sandalwood.
- Pair 3 is correctly matched: Babool (Acacia nilotica) is a characteristic tree of Tropical Thorn Forests. These forests occur in semi-arid areas with less than 50 cm of rainfall. The vegetation consists of stunted trees and bushes with deep roots and thorns to conserve moisture. Other examples include Ber, Wild Date Palm, Khair, Neem, and Khejri.
- Pair 4 is correctly matched: Silver Fir is a typical tree found in Montane Forests (specifically the Himalayan temperate forests). These forests are found at altitudes between 1500 and 3000 meters. Other trees in this zone include Pine, Deodar, Spruce, and Cedar.
Key Takeaway: Vegetation types are strictly determined by climatic parameters: Evergreen forests (High rainfall) contain Mahogany; Deciduous forests (Moderate rainfall) contain Teak; Thorn forests (Arid) contain Babool; and Montane forests (Altitude-based) contain Silver Fir.
