Which is a density dependent factor? a. natural disaster b. space c. flood d. fire

Your awsner is B. Space :)

The correct answer is option B which is space.

Explanation:Density-dependent factors are factors which are related to the size of the population. The population size is the limiting factor for that factor.Here for example flood is not the density-dependent factor as the flood affects both the small size and the large size population equally.But in the case of space, space is dependent on the size of the population. Higher the population size lower the space.Hence space is the correct answer.

The right answer is c.sandstone.
