O The area is being overfished.

O The species is likely to face extinction.

O There is no other place for that species to live.

O Food supply is high and the number of predators low.

Answers

Hence, the correct option is "Food supply is high and the number of predators low."

Answer:

D; Food supply is high and the number of predators low.
