Question

which of these factors could lead to the rapid growth of a population? Limited food supply, smal amount of space, natural disaster, lack of predators

Answer 1

Lack of predators.
There would be lesser predators feeding on that certain animal allowing it to reproduce, leading to a rapid growth of population

Hope this helps :)

Answer 2

lack of predators because the rest of the answers will lead to a population decreasing but without any predators a species will continue to expand.
