Answer 2

$\bf \underline{ \huge \color{red} Answer}$

Forests in general are known as ‘lungs of Earth’ because they absorb large amounts of carbon dioxide and release large amounts of oxygen due to photosynthesis.

The Amazon Rainforest in particular is known as ‘the Lungs of the World’ because it sucks up global emissions of carbon dioxide, and about 20% of earth’s oxygen is produced by the Amazonia.

However, decomposition of plant matter absorbs almost as much oxygen as the trees produce. It’s probably more accurate to think of them as having a cooling effect on the global climate, as they absorb a huge amount of heat from the sun.
