What are the levels of the rainforest?

Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.

Why is there high levels of biodiversity in tropical rainforests?

The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.

Why rainforest has a high level of biodiversity?

Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.

What are the three levels of biodiversity?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.

What is the biodiversity in the Amazon rainforest?

The Amazon Rainforest and Biodiversity

As an ecosystem, the Amazon is one of the most biodiverse places on earth. Over 3 million species live in the rainforest, and over 2,500 tree species (or one-third of all tropical trees that exist on earth) help to create and sustain this vibrant ecosystem.

Which ecosystem has highest biodiversity?

Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.

What is biodiversity and how does it affect the Amazon rainforest?

Amazon biodiversity also plays a critical role as part of global systems, influencing the global carbon cycle and thus climate change, as well as hemispheric hydrological systems, serving as an important anchor for South American climate and rainfall.

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 3 layers of 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. Each layer is home to many different animals.

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.
