Question

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?
clear cutting the rainforest
limited food source
susceptibility to disease
increase in population of Liophis epinephelus

Answer 1

Clear cutting the rainforest.

Explanation: density-independent factors are abiotic events or disturbances that affect populations regardless of their size (e.g., habitat destruction, weather, fires). Limited food, disease susceptibility, and increases in predator numbers are density-dependent (their effects change with population density).
