Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus . Which is most likely a density-independent factor that affects the poison dart population in the rainforest?

A density-independent factor affects a population regardless of how crowded it is. Clear cutting the rainforest is a habitat disturbance that can affect poison dart frogs whether their population is large or small. Limited food, disease, and an increase in predators generally affect populations in ways that depend on population density.
