Photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugarhttp://wiki.answers.com/wiki/Sugar, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in Archea. Photosynthetic organisms are called photoautotrophs, since they can create their own food. In plants, algae and cyanobacteria photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesis is vital for life on Earth. As well as maintaining the normal level of oxygen in the atmosphere, nearly all life either depends on it directly as a source of energy, or indirectly as the ultimate source of the energy in their food.

What is known as 'the lungs of the Earth'?
Forests.
why are equatorial forests important ?
These are the lungs of the Earth.
Forests are the lungs of the earth how long do you agree?
No, algae give off more oxygen than trees do.
Why forest are called lungs of the earth?
Forests are called the lungs of the Earth as they give us oxygen. Earth actually do not have any lung but forest acts as a lung. Like when we inhale oxygen, this oxygen goes into lungs and when we exhale carbon dioxide, this gas is exhaled from lungs. Similarly, forest exhale oxygen and inhale carbon dioxide. So, the forest acts a lung.
Is the rainforest called earth's lungs an accurate description?
No, it is not.Rain forests take in carbon dioxide from the atmosphere and release oxygen. Human and animal lungs do the exact opposite.
How do rainforests help us when you are ill?
many medicines come from the rainforests
Why Save your Forests?
We have to save our forests because its the Earths Lungs. If we cut them down Global Warming will kick in. We have to save our forests because its the Earths Lungs. If we cut them down Global Warming will kick in.
Why must you save the rainforest from being cut down?
The rainforest as well as other forests consist of animal habitats. By destroying forests, animal lives are being sacrificed. Forests are also known as the Earth's lungs because trees and plants purify the air.
Why the equatorial rain forests are called lungs of the world?
"Lungs of the world" is a catchy phrase but shows a lack of understanding of one of lungs or forests. Lungs take in air and remove oxygen and exchange it with carbon dioxide then expel it. Forests take in carbon dioxide and expel oxygen - the opposite process. Forests might be called "the air hose of the world" or "the Scuba tank of the world", but this doesn't seem to be as catchy a slogan.

Can you tell why the evergreen forest is like the lungs of the earth?
Forests are often referred to as "the lungs of the earth", probably by folks who have no idea about what lungs do except that it has something to do with air. Lungs extract oxygen from the air and provide it to the body for conversion of food (e.g. sugar) to carbon dioxide. Trees absorb carbon dioxide and convert it to oxygen and sugars through photosynthesis - the dead opposite of the lung/body function. Trees might better be called the "anti-lungs" of the Earth as they do this opposite function. Even calling them the scuba tanks of the Earth might be more correct as they supply oxygen to living organisms. Most accurate would be to call them the oxygen factories.
