Why is the rainforest's called the lungs of the world?

Answer 1

Because in the rainforest there is alot of trees and trees give off oxygen. If there are no trees there is no oxygen and without oxgen you cant breath and then you die. Thatz wy the rainforest is called the lungs of the planet since there is alot of trees in that one area.

Answer 2

Plants are the exact opposite of the function of our lungs. Plants are considered the lungs of the earth because plants produce oxygen, which is necessary for all life, so in essence, since our lungs keep us alive and trees keep our lungs alive we can consider trees to be a part of our lungs existence.

A1: An animal's lungs are the organs that pull an essential gas out of the atmosphere (oxygen) and spread it around the organism where it's needed.

B1: If the lungs stop, you have the death of the system-- the organism dies.

A2: Viewed as a whole, the plants on Earth pull an essential gas out of the atmosphere (carbon dioxide) and spread it around where it's needed-- each plant feeding itself, but at a larger scale also making possible all higher chemistry, by being food.

B2: If the plants stop, then you have the death of the system-- namely everything on Earth that eats plants, or that eats the things that eat the plants.

(For purposes of simile, we're leaving out animals that don't have lungs-- fish who pull in oxygen via gills, etc.)

Answer 3

Trees create a balance with animals, as they take in carbon dioxide and release oxygen.

In actual fact, though, the oceans could be seen as the lungs of the earth, because phytoplankton (plankton types that are plants not animals) produce as much as 70% of the oxygen we need through this same process. This is why it is so important to protect ocean ecosystems...

Answer 4

Probably because trees "breathe" in carbon dioxide and "breathe" out oxygen, and there are LOTS of trees in a rainforest. Technically though there is far more oxygen produced worldwide by algae in the ocean than there is by trees, but it's still a nice analogy.

Answer 5

They produce oxygen through photosynthesis. No! Just the opposite, lungs use oxygen and produce CO₂. The same goes for the oceans producing 25% of the worlds oxygen, to be used for our lungs.

Answer 6

Plants are the lungs of the earth because they use carbon dioxide to photosynthesize and give off oxygen.

Answer 7

because they take in carbon dioxide and let out oxigen

Answer 8

because they clean the air
