“Leaf litter decomposes faster than in any other biome and as a result the soil surface is often almost bare. Apart from trees, the vegetation is largely composed of plant forms that reach up into the canopy vicariously, by climbing the trees or growing as epiphytes, rooted on the upper branches of trees.” This is the most likely description of

D.tropical rain forest
A.coniferous forest
C.mangrove forest
B.dry deciduous forest

Correct Answer: Option D

The description points to a tropical rainforest due to the following characteristics:

  • Rapid Decomposition: High temperatures and humidity in tropical rainforests accelerate decomposition by bacteria and microorganisms. Leaf litter decomposes very quickly, resulting in a nearly bare soil surface.
  • Nutrient Cycling: Nutrients released from decomposition are rapidly absorbed by plants. Heavy rainfall leaches remaining nutrients, leading to infertile and acidic soil.
  • Epiphytes: Epiphytes thrive in rainforest canopies, obtaining nutrients from air and water rather than the soil. They grow on tree branches to access sunlight.

Hence, the correct answer is (d) tropical rain forest.
