High mass per unit volume.
Space and food sources are density-dependent factors.
density dependent
A density dependent factor is a factor that is affected by the amount of organisms in a population. An example of this would be sickness, as the higher the density is, the more easily the sickness will spread.
Space
Space
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.
Space
Parasitism
yes
Space and food sources are density-dependent factors.
No, a tornado is not a density dependent factor. Density dependent factors are biotic factors that influence population size based on population density, while tornadoes are weather phenomena that are not influenced by population density.
A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my Biology book.
