Answer 1

Answer:

• Plants play a very important role on Earth.

• They can be considered as the reason why all living organisms can survive on Earth.

• Plants purify as they release oxygen in the atmosphere through the process of photosynthesis.

• The oxygen is used by animals and plants during respiration.

• Plants have a unique ability of using carbon dioxide (released as a result of respiration and by burning fuels) during the process of photosynthesis.

• For this reason forests and plants are called ‘green lungs’ or ‘lungs of the earth’.

• Hence, we can conclude that Plants are the Lungs of Earth.
