Question

which argument best predicts the impact of a lionfish control program on the stability of the ocean ecosystem?

a it would increase the population of lionfish, resulting in a decrease of small fish and crustaceans. the population of lionfish would eventually be reduced to zero resulting in ecosystem stability.

b it would increase the population of lionfish, resulting in a decrease of small fish and crustaceans. the populations of lionfish and their prey will vary less over time resulting in ecosystem stability.

c it would decrease the population of lionfish so that more small fish and crustaceans live. the populations of lionfish and their prey will have a characteristic pattern resulting in ecosystem stability unless the program ends.

d it would decrease the population of lionfish so that more small fish and crustaceans live. the populations of lionfish and their prey will eventually become equal resulting in ecosystem stability and the program can end.

Explanation:

A lionfish control program aims to reduce the invasive lionfish population. This allows their prey (small fish, crustaceans) to recover. The graph shows a stable cyclical pattern between predator (lionfish) and prey populations once the system balances, which would persist as long as the control program supports this dynamic. Option A is wrong because lionfish wouldn't be reduced to zero, and B is incorrect as the program doesn't increase lionfish. Option D is wrong because populations don't need to be equal for stability.

Answer:

C. It would decrease the population of lionfish so that more small fish and crustaceans live. The populations of lionfish and their prey will have a characteristic pattern resulting in ecosystem stability unless the program ends.
