The figure titled "Marine Species Diversity vs. Ocean Depth" is a scatter plot that illustrates the relationship between ocean depth in meters and the number of marine species. The x-axis represents the ocean depth ranging from 0 meters to 10,000 meters, while the y-axis represents the number of species ranging from 0 to 2,500.

The plot reveals a clear, negative trend indicating that marine species diversity decreases as the ocean depth increases. At the shallowest depth of 0 meters, the number of species is highest at 2,300. As the depth increases to 50 meters, the number of species slightly declines to 2,100. This downtrend continues steadily as the depth increases: 

- At 100 meters, the species count is 1,900.
- At 200 meters, it reduces further to 1,500.
- By 500 meters, the number of species drops significantly to 1,000.
- At 1,000 meters, only 750 species are present.

The decline becomes even more pronounced beyond 1,000 meters. For instance:

- At 2,000 meters, the species count falls to 500.
- At 3,000 meters, 400 species are recorded.
- At 4,000 meters, the count is 300.
- At 5,000 meters, it further drops to 200.

In the deeper ocean zones:

- At 6,000 meters, only 150 species are observed.
- At 7,000 meters, the number declines to 100.
- At 8,000 meters, the count is as low as 50.
- At 9,000 meters, it drops to just 25 species.
- At the maximum depth of 10,000 meters, only 10 species are found.

The scatter plot uses blue circles to mark data points, which are evenly distributed along the depth axis but display a marked decline as depth increases, visually emphasizing the correlation between increasing depth and decreasing species diversity. The data points are presented clearly with appropriate distances between them to depict how species diversity diminishes with depth comprehensively.

        "question": "What is the general trend in marine species diversity as ocean depth increases?",
        "answer": "Marine species diversity decreases as ocean depth increases.",
        "explanation": "The plotted points show a clear downward trend indicating that the number of marine species decreases consistently with increasing ocean depth."
    },
    {
        "question": "At what ocean depth is the diversity of marine species the highest?",
        "answer": "0 meters",
        "explanation": "The highest number of species is observed at 0 meters depth, where the number of marine species is 2300."
    },
    {
        "question": "How many species are present at 1000 meters depth?",
        "answer": "750",
        "explanation": "According to the figure, the point corresponding to 1000 meters depth indicates there are 750 species."
    },
    {
        "question": "How does species diversity change between 2000 meters and 5000 meters depth?",
        "answer": "Species diversity decreases from 500 to 200.",
        "explanation": "The number of species drops from 500 at 2000 meters to 200 at 5000 meters, indicating a significant decrease in marine species diversity as depth increases."
    },
    {
        "question": "Is the decrease in the number of species constant as the depth increases?",
        "answer": "No, the rate of decrease in the number of species changes with depth.",
        "explanation": "Initially, the decrease is more rapid (e.g., from 2300 to 1500 species between 0 and 200 meters). However, after 500 meters, the decrease becomes less steep, showing a gradual reduction in species diversity."
    },
    {
        "question": "What depth range shows the sharpest decline in species diversity?",
        "answer": "0 to 200 meters",
        "explanation": "The number of species drops from 2300 to 1500, which is a decrease of 800 species, indicating the sharpest decline in species diversity."
    },
    {
        "question": "How many species are there at 8000 meters depth?",
        "answer": "50",
        "explanation": "The plot shows that at 8000 meters depth, the number of species is 50."
    },
    {
        "question": "At what depth do marine species numbers drop below 1000?",
        "answer": "At 500 meters depth",
        "explanation": "The plot shows that at 500 meters depth, the number of species is exactly 1000. Below this depth, the number of species continues to decrease."
    },
    {
        "question": "What is the diversity of marine species like at the deepest measured depth?",
        "answer": "10 species",
        "explanation": "The plot indicates that at 10000 meters depth, there are 10 species."
    },
    {
        "question": "What might be a potential cause for the decrease in species diversity with increasing depth?",
        "answer": "Decreasing light, temperature, and food availability",
        "explanation": "As depth increases, environmental factors such as light, temperature, and food availability typically decrease, which can lead to lower species diversity."
