Answer 1

Answer:

B. 1 and 2

Tropical Evergreen Forests

• Geographical Distribution: These forests are typically found in regions experiencing consistently high temperatures and humidity throughout the year. They thrive in areas receiving abundant rainfall, generally exceeding 200 cm (approximately 78.7 inches) annually. Such conditions are often found near the equator.
• Structural Characteristics: The forest canopy is dense and multi-layered, creating a complex vertical structure. This stratification typically includes:
  • An upper emergent layer with very tall trees that can reach heights of up to 60 meters (around 200 feet).
  • A dense middle layer composed of shorter trees and large shrubs.
  • A lower layer with smaller shrubs and shade-tolerant vegetation.
  This layered structure leads to limited sunlight reaching the forest floor.
• Biodiversity: Tropical evergreen forests are known for their exceptionally high biodiversity, housing a vast array of plant and animal species.
• Lumber and Economic Importance: While many species exist, commercially valuable timber species are often scattered. Obtaining and transporting timber can be challenging due to the dense undergrowth and remote locations.
• Contrast with Other Regions: These forests are distinct from vegetation found in semi-arid regions. For instance, semi-arid regions like parts of Southwest Punjab typically support dry deciduous forests, scrubland, or grasslands adapted to low rainfall and drier conditions.
