Final answer:
The Amazon rainforest is referred to as the 'lungs of the Earth' because it produces oxygen and reduces carbon dioxide. Trees in the rainforest use photosynthesis to absorb carbon dioxide and release oxygen into the atmosphere. The rainforest also acts as a carbon sink, helping to regulate the Earth's climate.
Step-by-step explanation:
The Amazon rainforest is often referred to as the "lungs of the Earth" because it plays a vital role in producing oxygen and reducing carbon dioxide in the atmosphere. Just like how our lungs take in oxygen and release carbon dioxide, the Amazon rainforest absorbs carbon dioxide through photosynthesis and releases oxygen back into the air.
The rainforest is home to numerous plant species, especially trees, which undergo photosynthesis. During photosynthesis, trees use sunlight, carbon dioxide, and water to produce glucose and oxygen. The oxygen is released into the atmosphere, while the glucose is used as energy for the tree.
In addition to being a major oxygen producer, the Amazon rainforest also helps regulate the Earth's climate. It acts as a carbon sink, meaning it absorbs more carbon dioxide than it emits. This helps in reducing the greenhouse effect and mitigating climate change.
