Answer 2

Hey mate ,
This is the answer

Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies hugely with year-to-year variations in the climate. A new paper published this week in the journal Nature shows that these variations reveal how vulnerable the rainforest is to climate change.
