Answer:
The correct answer is option B which is space.
Step-by-step 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.
