Tropical rainforests are characterized by high temperatures, high rainfall, and high primary productivity throughout the year. This leads to dense vegetation with multiple layers and very large, long-lived trees, resulting in a high accumulation of plant biomass per unit area compared to other terrestrial ecosystems.

- "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
