Answer 1

Correct Answer - Option 1 : Tropical evergreen forest of Brazil.

The tropical evergreen forest of Brazil is called the 'lungs' of the earth

Amazon Rainforest:

• Amazon rain forest is the world's largest rainforest.
• The basin is roughly the size of the forty-eight contiguous United States.
• It covers some 40 percent of the South American continent and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname, as well as French Guiana, a department of France.
• Amazon is made up of a mosaic of ecosystems and vegetation types including rainforests, seasonal forests, deciduous forests, flooded forests, and savannas.
• The basin is drained by the Amazon River, the world's largest river in terms of discharge, and the second-longest river in the world after the Nile.
• The river is made up of over 1,100 tributaries, 17 of which are longer than 1000 miles, and two of which (the Negro and the Madeira) are larger, in terms of volume than the Congo river.
• Amazon rainforest is popularly called the 'lungs of the planet earth' because its vegetation continuously recycles carbon dioxide into oxygen.
