Question

Why are plants called the lungs of the earth explain?

Answer 1

plants in general are known as ‘lungs of Earth’ because they absorb large amounts of carbon dioxide and release large amounts of oxygen due to photosynthesis.

The Amazon Rainforest in particular is known as ‘the Lungs of the World’ because it sucks up global emissions of carbon dioxide, and about 20% of earth’s oxygen is produced by the Amazonia.

However, decomposition of plant matter absorbs almost as much oxygen as the trees produce. It’s probably more accurate to think of them as having a cooling effect on the global climate, as they absorb a huge amount of heat from the sun.

Answer 2

Answer:

• Tropical rainforests are frequently referred to be the "lungs of the planet" because they typically breathe oxygen in and carbon dioxide out.
• But when the temperature changes from year to year, the amount of carbon dioxide they create or absorb varies greatly.
• Burning fossil fuels and deforestation result in an annual increase in carbon dioxide.
• However, the rate at which it increases from one year to the next is dependent on whether tropical forests are absorbing carbon dioxide or releasing it, which in turn depends on whether the tropical environment was warmer and dryer than usual, or wetter and colder.
• As a result, the amount of carbon dioxide in the atmosphere provides a record of how the planet's lungs react to temperature changes.

These are the reasons of why plants are called the lungs of the earth.
