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 of the following factors is most likely a density-independent regulator of population growth of poison dart frogs in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus

Answer 1

The answer is A. Clear cutting the rain forest because it is a human activity and that does not depend on the population size of a place.

Answer 2

Answer:

The correct answer is CLEAR CUTTING THE RAIN FOREST

Explanation:

The factors that affect the survival of living organisms can be divided into two major groups, which are density dependent and density independent factors. Density dependent factors refers to those factors that their impacts depend on the size of the population. Example of such factors are food availability, predation, migration and diseases.

Density independent factors on the other hand refers to those factors that affect population size regardless of their sizes. Examples of such factors are temperature, natural disasters, human activities, etc.

In the question given here, the clear cutting of the rain forest is brought about by human activity and is an example of density independent factor.
