Answer 2

Hello. This question is incomplete. The complete question is:

"Which of the following is a density-independent limiting factor?

a. earthquake , b. disease , c. emigration , d. parasitism"

Answer:

a. earthquake

Explanation:

Density-independent factors are those that are not influenced by the number of individuals in a population. Climate variables are a good example of this type of factor, but we can also cite the emergence of disease, migration and parasitism. These factors tend to cause sometimes drastic variations in population density. The carrying capacity of an environment can be influenced by these factors. Density-independent factors are most important in physically stressed ecosystems.

An earthquake is not an independent factor of density.
