Question

24. Determine whether the following factors are density-dependent or density-independent.
Drought
Disease
Temperature
Low pH
Prey population number
Predator population number
Competition
Loss of habitat

Choose A OR B FOR EACH OPTION. A. density-dependent B. density-independent

Answer 1

* Density-dependent factors are factors whose effects on the size or growth of the population vary with the population density, and these factors can have either a positive or a negative correlation to population size.

* Density independent factors are those that regulate population growth without depending on its density

density-dependent factors	density-independent factors
Disease	Drought
Prey population number	Temperature
Predator population number	Low PH
Competition	Loss of habitat
