Question

Which of the following rain forests is home to more than 40,000 species of plants, 3,000 of fishes, 1,300 species of birds, 427 species of mammals, 427 species of amphibians, 378 species of reptiles, and more than 1,25,000 invertebrates?
(A)Amazonian
(B)Tropical
(C)Arctic tundra
(D)Temperate

Answer 1

Hint: Rainforests are areas of tall, evergreen trees with a high amount of rainfall. Their environment is very suitable for a lot of organisms and therefore, the rainforests hold the majority of biodiversity of the Earth.

Complete answer:
The Amazonian rainforest is a moist broadleaf tropical rainforest in Brazil that covers most of the Amazon basin of South America and is home to more than 40,000 species of plants, 3,000 fishes, 1,300 species of birds, 427 mammals, 427 amphibians, 378 reptiles, and more than 1,25,000 species of invertebrates. The majority of the area of the Amazonian rainforest is in Brazil but its 13% of it is in Peru, 10% in Colombia, and some minor areas in Bolivia, Ecuador, French Guiana, Guyana, Suriname, and Venezuela. These rainforests hold the majority of Biodiversity and also more than 30 million people of 350 Different ethnic groups.

Additional information:
Tropical rainforests are in the areas of tropical climate in which there is no dry season and are mainly found between 10° north and south of the equator. They exhibit high levels of biodiversity, around 40% to 75% of all biotic species being indigenous to these rainforests. Also, these are known as "world's largest pharmacies" due to the high amount (over one-quarter of the total) of natural medicines discovered within them.
Arctic tundra is characterized by low temperature and short growing seasons of the plants and is located in the far Northern hemisphere and north of the taiga belt. They contain areas of the stark landscape and are frozen for much of the year. The biodiversity in these areas is low- the number is 1700 species of vascular plants and only 48 species of land mammals.
Temperate forests are found between tropical and Boreal regions in the temperate zone and are the second-largest biome on the planet covering 25% of the world's forest areas. The climate of these areas is highly variable depending mainly on the location of the forest.

So, the correct answer is "Amazonian".

Note: The wet tropical forests hold the most species diversity on the Earth and the Amazonian rainforest is one of them. As the largest tropical rainforest in America, it holds one in ten known species in the world that constitutes the largest collection of living plants and animal species in the world. One in five of all bird species and one in five of the fish species inhabit these Rainforests.
