Determine which examples are density-dependent population changes and which are density-independent population changes.
-A virus spreads through a population of wild dogs and 20 percent of the dogs die.

Question

Quizplus · Accepted Answer

The virus spreading through the population of wild dogs is a density-dependent population change because it is influenced by the density (or number) of dogs in the population. As more dogs are present, the likelihood of the virus spreading increases, which can lead to a decrease in the population size. The fact that 20 percent of the dogs die is a possible consequence of this density-dependent change.
