Answer 1

Answer:

C. 1 and 2

Tropical Evergreen Forests

• Characteristics: These forests are characterized by the absence of a fixed period for leaf shedding or flowering. This means trees continuously shed leaves and produce new ones throughout the year, maintaining a dense canopy.
• Vegetation: The dominant trees are hardwood species that yield valuable timber. Common examples include rosewood, mahogany, and ebony. Other notable species are rubber, cinchona, and palms.
• Location and Rainfall: Tropical evergreen forests are typically found in regions that receive heavy rainfall, generally exceeding 200 cm annually. They thrive in areas with high temperatures and humidity throughout the year.
• Distribution in India: In India, these forests are primarily located along the Western Ghats, the northeastern regions (Assam, Meghalaya, Nagaland, Tripura), the Andaman and Nicobar Islands, and the upper parts of the Mahanadi and Brahmaputra valleys.
• Edaphic Factors: These forests grow on well-drained soils, often found in alluvial plains, coastal areas, and hilly regions.
• Ecological Significance: They are known for their immense biodiversity, supporting a vast array of plant and animal species.
• Contrast with Other Forest Types: Unlike deciduous forests, which shed their leaves seasonally, evergreen forests retain their foliage year-round. The rainfall requirement of 70-100 cm mentioned in statement 3 is typically associated with tropical dry deciduous or tropical moist deciduous forests, not tropical evergreen forests.
