This population is growing exponentially. A population can only continue to grow exponentially when

• predators are exterminated.

• all resources are available without any limits.

• there is a shortage of habitats

• niches are already filled.

This population is in logistic growth. In logistic growth, a population that was growing rapidly stops growth and maintains/stabilizes its population size because

• the population has hit the ecosystem's carrying capacity.

• the number of prey suddenly increased.

• immigration increased.

• birth rate increased.
