Explanation:

To answer these questions, we would need the content of the article on the previous slides (which is not provided here). However, I can give general explanations based on typical knowledge about invasive species like lionfish:

Question 1: Why was the lionfish able to go from a very small initial population on the coast of Florida to taking over the Atlantic coast and Bahamas?

Lionfish are invasive species with no natural predators in the Atlantic/Bahamas ecosystem, allowing their population to grow unchecked. They also have a high reproductive rate (producing many eggs) and are generalist predators (eating a wide range of native fish and invertebrates), so they can quickly exploit new habitats. Additionally, human activities (like aquarium releases) introduced them, and the warm, nutrient - rich waters of the region support their growth.

Question 2: What happened to the native fish population as a result of the lionfish population booming?

As lionfish populations boom, native fish populations decline sharply. Lionfish prey on native fish (including juveniles of commercially and ecologically important species), reducing their numbers. This also leads to increased competition for food and habitat between lionfish and native species, further suppressing native fish populations.

Question 3: Why is it nearly impossible to get rid of the lionfish from their new territory?

Lionfish are hard to eradicate because they:

• Have a wide - ranging habitat (from shallow reefs to deeper waters), making complete removal difficult.
• Reproduce rapidly, so even if some are removed, their population can rebound quickly.
• Are skilled at hiding in complex reef structures, making them hard to detect and remove completely.
• Lack natural predators in the new ecosystem to control their numbers.

Question 4: Why is the lionfish population stable (kept in check) in their native environment?

In their native Indo - Pacific range, lionfish populations are controlled by natural predators (like groupers, sharks, or other large fish) that prey on them. There is also co - evolved competition and disease that limit their population growth, maintaining a balance in the native food web.

Question 5: How will it negatively affect the natural food web in the Atlantic coast and Bahamas if the lionfish out - compete and drive out all the original fish populations?

If lionfish eliminate native fish:

• Trophic cascades will occur: For example, if lionfish eat herbivorous fish, algae will overgrow (since there are fewer fish to graze on it), smothering coral reefs and reducing reef health.
• Predatory native fish that rely on the now - eliminated species for food will starve or be forced to leave, disrupting higher trophic levels.
• Commercial and recreational fisheries will suffer due to the loss of target species, impacting local economies and food security.

Since the actual article’s details are missing, these are general explanations. To provide precise answers, the specific information from the article (about lionfish’s adaptations, local ecosystem details, etc.) would be needed.
