Question

based on your understanding of the passage and text features, match each action to its impact on the great barrier reef. oceanic acidification coral bleaching overfishing commercial fishing practices warming of the earths core temperature carbon emissions and atmospheric

Explanation:

To solve this matching problem, we analyze each action and its typical impact on the Great Barrier Reef:

1. Oceanic Acidification

Oceanic acidification is primarily caused by carbon emissions and atmospheric changes (like increased CO₂ dissolving in seawater, lowering pH). This affects coral skeletons and marine life in the reef.

2. Coral Bleaching

Coral bleaching occurs when corals expel symbiotic algae (zooxanthellae) due to stress, often from warming of the Earth’s core temperature (global warming, which raises ocean temperatures).

3. Overfishing

Overfishing is driven by commercial fishing practices (excessive or unsustainable fishing), which disrupt the reef’s ecosystem by depleting fish populations that support coral health.

Final Matches:

• Oceanic Acidification → carbon emissions and atmospheric changes
• Coral Bleaching → warming of the Earth’s core temperature
• Overfishing → commercial fishing practices

(Note: If the third impact option is “carbon emissions and atmospheric changes” (partially visible), confirm the full text, but the above logic follows scientific consensus.)
