Question

How did the lack of sea urchins change the effect of lionfish on the reef?

Answer 1

The lack of sea urchins causes the accumulation of algae on the reef leading to the growth of fish populations. The process significantly increased the invasion of lionfish in the reef. As the reef significantly depends on these fishes and the lionfish feeds on these fish species, the lionfish destroy the reef.
