Answers
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.
The study reveals a new way to find out how sensitive biological systems are to changes in climate. The key was to learn how to read the year-to-year variations in the concentration of carbon dioxide in the atmosphere
In the northern region near the equator in brazil Rainforest are seen. We know that trees take Carbon dioxide and throw out oxygen. As rainforest are in larger quantity, this tress wre more and this process of Carbon dioxide and oxygen moves steadily.
