What are the four layers of the tropical rainforest from top to bottom?
We will be referring to four layers. From top to bottom, they are: the emergent layer, the canopy, the understory, and the forest floor. Though the layers are related, each is a distinct world.
What are the four layers of the canopy?
There are four different layers of the rain-forest, each marked with different characteristics. They include the emergent layer, the upper canopy, the under-story (lower canopy), and the forest floor. Emergent Layer: The emergent layer has trees which are spaced widely.
What are the main layers of a forest?
Vertically forests are divided into four layers as follow:
- Emergent Layer.
- Canopy layer.
- Understory layer.
- Forest floor.
What are the 5 forest layers?
Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor. Each layer has its own unique plant and animal species interacting with the ecosystem around them.
What is canopy and understory?
The canopy is the dense ceiling of closely spaced trees and their branches, while the understory is the term for more widely spaced, smaller tree species and juvenile individuals that form a broken layer below the canopy.
What is the first layer of the rainforest?
the emergent layer The first layer of the rainforest is the emergent layer. This consists of the tallest trees that stretch their limbs to the sky at heights of up to 200 feet over the forest floor.
What is the shrub layer?
Definition of shrub layer : the undergrowth of a forest consisting usually of plants from 3 to about 15 feet in height and including both shrubby vegetation and seedling trees.
What is the third layer of the rainforest?
The tops of very tall trees in the forest form the third layer, the canopy. Canopy trees may reach a height of 150 feet. Slender trunks branch out into leafy crowns, forever reaching for sunlight. Some canopy trees, stretching to get above the crowd, may grow to 200 feet.
What is the second highest layer of a rainforest called?
The second layer of the rainforest is the canopy layer. Think of it as a roof that offers protection for everything that lies below. This is found beneath those trees that reach far above. The trees, leaves, and vines are closely knit together, providing excellent shelter for an abundance of life forms.
What is herb layer?
Definition of 'herb layer' 1. a thickness of some homogeneous substance, such as a stratum or a coating on a surface. 2. one of four or more levels of vegetation defined in ecological studies: the ground or moss layer, the field or herb layer, the shrub layer, and one or more tree layers.
What is canopy layer?
Located right underneath the top layer of the rainforest, known as the emergent layer, is the layer known as the canopy. A canopy is a kind of covering; in this case, the rainforest canopy provides shelter and shade for the two rainforest layers beneath it.
What are the 5 layers of rainforest?
Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor. Each layer has its own unique plant and animal species interacting with the ecosystem around them.
What are the 7 layers of the rainforest?

What is the 3rd layer of the rainforest?
There are 3 levels in the tropical rainforest. The canopy is the top layer that covers most of the forest. The middle level is called the understory, and the bottom level is called the forest floor.
What is the third layer of the rainforest called?
the canopy The tops of very tall trees in the forest form the third layer, the canopy. Canopy trees may reach a height of 150 feet. Slender trunks branch out into leafy crowns, forever reaching for sunlight. Some canopy trees, stretching to get above the crowd, may grow to 200 feet.
What is the understory layer?
Several meters below the bottom of the canopy is the understory, a layer made up of young trees, short species of trees, shrubs, and soft-stemmed plants. The understory varies a lot from rainforest to rainforest.
Why does the rainforest have 4 layers?
These plants provide food and shelter for a huge variety of animals. Rain forests are divided into four layers, or stories: emergent layer, canopy, understory, and forest floor. Each layer receives a different amount of sunlight and rainfall, so different types of animals and plants are found in each layer.
What are the 3 types of rainforests?
The types of rainforest include: Tropical mangrove forests. Temperate rainforests. Seasonal rainforests.

What is the canopy layer?
The canopy layer is made up of the overlapping leaves and branches of the trees of the rainforest. Scientists estimate that 60-90% of life in the rainforest can be found in the canopy layer, making it the richest habitat for plant and animal life.
