Options

A. One - third
B. One - fourth
C. One - fifth
D. One - sixth

Answer

To solve the question regarding the contribution of the Amazon rainforest to the total oxygen in Earth's atmosphere, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Amazon Rainforest's Role**: The Amazon rainforest is often referred to as the "lungs of the Earth" due to its significant role in producing oxygen through photosynthesis.

2. **Determine the Area of the Amazon Rainforest**: The Amazon rainforest covers an area of approximately 5.5 million square kilometers. This vast area contributes significantly to the global oxygen supply.

3. **Understand Photosynthesis**: During photosynthesis, plants, including those in the Amazon rainforest, convert carbon dioxide and water into glucose and oxygen, thereby releasing oxygen into the atmosphere.

4. **Estimate Oxygen Production**: It is estimated that the Amazon rainforest produces about one-fifth (1/5) of the total oxygen in Earth's atmosphere. This is a crucial statistic that highlights the importance of the Amazon in maintaining atmospheric oxygen levels.

5. **Conclude the Answer**: Based on the information gathered, we can conclude that the Amazon rainforest produces **one-fifth (1/5)** of the total oxygen in Earth's atmosphere.

### Final Answer:
The Amazon rainforest is estimated to produce **one-fifth (1/5)** of the total oxygen in Earth's atmosphere.
