Detailed explanation-1: -Forests are called lungs of the earth because they absorb an enormous amount of carbon dioxide that circulate in the atmosphere. They are effective and thus protecting those lungs is crucial if we are to defend the plant biodiversity and fight global warming.
Detailed explanation-2: -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.
Detailed explanation-3: -It absorbs about 25% of atmospheric carbon dioxide. It produces 6 per cent of total oxygen in Earth’s atmosphere through the process of photosynthesis. So, for these reasons Amazon rainforest is called the lung of the planet earth.
Detailed explanation-4: -Final answer: c. Amazon rainforest.
Detailed explanation-5: -The plants release oxygen through the process of photosynthesis. The plants help to provide oxygen to animals for respiration. They also maintain the balance of oxygen and carbon dioxide in the atmosphere. That is why forests are called green lungs.
