8.4 Effect of Density of Populations
Notes
- Density-dependent factors have a stronger effect in dense populations: competition, disease, predation.
- Density-independent factors affect populations regardless of density: weather, fire.
Practice
Disease spreading faster in crowded populations is:
Depends on crowding.
A hurricane killing much of a population is:
Not related to density.
As density increases, competition for food usually:
Fewer resources each.
