• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer 1

Answer:

A. 1 and 2

Tropical Evergreen Forests:

• Climate: These forests thrive in regions receiving **annual rainfall exceeding 200 cm** and maintaining a **mean annual temperature above 22°C**.
• Characteristics: They are characterized by a dense, multi-layered canopy with trees reaching heights of up to 60 meters. The vegetation is evergreen, meaning trees do not shed their leaves seasonally.
• Biodiversity: These forests support a rich diversity of flora and fauna due to the consistent warm and wet conditions.
• Location: Found along the Western Ghats, Northeast India, and the Andaman and Nicobar Islands.

Tropical Semi-Evergreen Forests:

• Characteristics: These forests represent a transition between evergreen and moist deciduous forests. They contain a **mix of evergreen and moist deciduous tree species**.
• Canopy: While predominantly evergreen, they have a significant presence of deciduous trees that shed leaves for a short period. The undergrowth is typically dense and includes evergreen species.
• Climate: They are found in areas with slightly lower rainfall than evergreen forests, typically between 150-200 cm annually, but still with warm temperatures.
• Location: Often found adjacent to tropical evergreen forests, in regions like the Eastern Himalayas, parts of the Western Ghats, and the Andaman Islands.
• Distinction from Arid Regions: These forests are found in humid, high-rainfall zones and are **not located in the arid regions of Rajasthan and Gujarat**, which are characterized by dry deciduous and thorny forests.
