The fifth and final layer is the herb layer which is the forest floor. The forest floor is mainly bare except for various plants, mosses, Lycopods and ferns. The forest floor is much more dense than above because of little sunlight and air movement. [2] Plant species native to the tropics found in tropical ecosystems are
A tropical rainforest typically has a number of layers, each with different plants and animals adapted for life in that particular area. Examples include the emergent, canopy, understory and forest floor layers. [19] [20]
An area of the Amazon rainforest in Brazil. The tropical rainforests of South America contain the largest diversity of species on Earth. [1] [2] Tropical rainforest climate zones (Af). Tropical forests: from the UN FRA2000 report. Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south ...
About half of the world's tropical rainforests are in the South American countries of Brazil and Peru. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rainforests.
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
Most of the interior of the Amazon basin is covered by rainforest. [6] The dense tropical Amazon rainforest is the largest tropical rainforest in the world. [2] It covers between 5,500,000 and 6,200,000 square kilometres (2,100,000 and 2,400,000 sq mi) of the 6,700,000 to 6,900,000 square kilometres (2,600,000 to 2,700,000 sq mi) Amazon biome.
It is one of the tallest tropical tree species: the tallest measured specimen is 85.8 m [6] or 88 m [2] (281 or 289 ft) tall. These grow mostly in lowland rainforests where they tower over the canopy. Like most tall rainforest trees they have huge buttress roots to support their weight. This is because the majority of the nutrients in ...
This is a list of plants found in the wild in Amazon Rainforest vegetation of Brazil. The estimates from useful plants suggested that there are 800 plant species of economic or social value in this forest, according to Giacometti (1990). [1]
