Tropical Rainforest and Its Layers
With regards to tropical rainforest layers, there are some four levels to it and they are the emergent layer, the upper  canopy layer, the understory layer and the forest  floor. The emergent layer include trees that are some 100 to 250 feet in height and possess umbrella-shaped canopies which grows beyond the forest. This level contains trees which have small, pointed leaves. Some of the tropical rainforest trees present in this layer are Balizia elegans,  Hieronyma alchormeoides and Dipteryx panamensis and others. These trees have shallow root system and buttress to support their large sizing.

Next in the tropical rainforest layers would be the the canopy layer which include trees which are 60 to 130 feet in height with leaves which are tall and wide  shaped. It is this layer that houses the largest variety of rainforest animals as a result of high accessibility to food for them. Large numbers of tropical rainforest trees like epiphytes such as bromeliads, orchids, lichens and mosses is found  in the canopy layer of tropical rainforest.

The understory comes after the top canopy and consists of trees which are 60 ft. tall and this level of the tropical rainforest constantly stays within the shade. Plants, shrubs, canopy trees in addition to small trees are available in this layer and it allows very little motion of air.

The very last one of the tropical rainforest layers will be the forest floor that typically stays in full shade. This scantily lit level of the tropical rainforest have few growth of tropical rainforest trees like herbs and shrubbery. This level of the forest includes a pretty thin layer of decaying organic and natural  matter that is quickly converted by worms, termites and fungi. It is because of the extremely low transmission of natural light the forest floor contains less plant life.
