Density-Dependent
Referring to factors whose effects on a population vary depending on the population density.
Population Control
Strategies or policies aimed at regulating the growth rate of a population to ensure sustainability and prevent overuse of resources.
Predation
The biological interaction where one organism, the predator, feeds on another organism, its prey.

Final Answer :
C
Explanation :
Predation is a density-dependent population control since as the population size of prey increases, predators will have more food available and their population size may also increase. This can lead to a decrease in the population size of prey as they become more vulnerable to predation. The other options listed (fire, drought, human destruction of habitat) are not directly related to the population density of the species and are therefore not density-dependent population controls.
