Answer:
Lionfish are native to the Indo-Pacific region. However, a hurricane caused six fish from an aquarium to accidentally be swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to rapidly increase in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of ocean. These fish have predators such as sharks and scorpion fish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food. Their one predator is humans, who have recently started fishing them for food. In the Atlantic Ocean, algae and seaweed are producers. Small fish, crabs, and other crustaceans make up the first and secondary consumers. Sharks and orcas are some of the larger predators, which are also consumers. Bacteria and fungi are the decomposers that break down food. Lionfish are consumers because they eat fish and small crustaceans.
