Which of the following forests is known as the lungs of the planet earth?

Explanation

The most important pattern of biodiversity in latitudinal gradient in diversity. Diversity is said to be maximum at the tropic because of the following reasons.
(i) Warm tropical regions on either side of the equator posses congenial habitats for living organisms.
(ii) Environmental conditions of the tropics are favourable for, speciation and also support variety and number of organisms.
(iii) The temperature range from `25^(@)C` to `35^(@)C` is ideal for metabolic activities of living organism.
(iv) Average rainfall is more than 200 mm/year.
(v) Climate, seasons, temperature, humidity, photoperiod are more or less stable and encourage number of variety of species.
(vi) Rich resource and nutrient availability is an added advantages.
Tropical rain forests occupied about 14% of earth's land surface earlier which is reducing now. The Amazon Rain forest is a classical example of a Tropical Rain forest is a vast area harbouring millions of species. It is the largest Tropical forest in the world with all the features as listed above. Thus it is aptly called as "Lungs of the Planet". It is being destroyed now and replaced for agriculture and Human settlement.
