Which of the Following is Most Likely to Contribute to Density-Dependent

Question

Which of the following is most likely to contribute to density-dependent regulation of populations?
A)the removal of toxic waste by decomposers
B)intraspecific competition for nutrients
C)earthquakes
D)floods
E)fires

Accepted Answer

Intraspecific competition for nutrients refers to competition among individuals of the same species for resources such as food, water, and shelter. This is a common example of density-dependent regulation, where as population density increases, competition for resources becomes more intense, and this can limit population growth. The other choices - removal of toxic waste by decomposers, earthquakes, floods, and fires - are not direct examples of density-dependent regulation of populations.
