write the main features of tropical rain forest
Answers
The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness).
A tropical rainforest has four distinct layers: the emergent layer, the canopy, the understorey and the forest floor. The rivers and streams in a rainforest can also be considered one of the structural features. The climate of a rainforest is one of its main features.

Because of the lack of seasonal differences, due to the geographical location of the forests, and the high humidity level the vegetation is luxuriant here. The recurring features of rainforests are basically the following:
high animal and vegetal biodiversity
evergreen trees
dark and sparse undergrowth interspersed with clearings
scanty litter (organic matter settling on the ground)
presence of “strangler” creepers (e.g. Ficus spp.)
presence of “buttresses” (i.e. large winged ribs at the base of trunks) and spindly roots in trees living in often-flooded areas.
