A density-dependent limiting factor is one whose effect

A.increases as the population gets denser
B.is identical at all densities
C.only affects small populations
D.always kills the same number of individuals

Explanation

Core Concept

A density-dependent factor is one whose effect on population growth changes with population density. Competition for limited resources and transmission of some diseases commonly become stronger as density rises. Other interactions can be more context-dependent, so the definition matters more than assuming every example increases in exactly the same way.

Correct Answer

Aincreases as the population gets denser
