Limiting Factors?
A limiting factor is an environmental factor that tends to limit population size. There are two different types of limiting factors: density-dependent and density-independent. The difference between the two is that density-dependent limiting factors rely on population size; the larger a population, the bigger impact a density-dependent limiting factor will have. Density-independent limiting factors do NOT rely on population size, instead they affect all populations equally.

Density-Dependent Factors
A limiting factor that depends on population size. Density-dependent limiting factors include:

Density-Independent Factors
Affect all populations in similar ways, regardless of the population size.
density-independent limiting factors include:
• unusual weather
• natural disasters
• seasonal cycles
• certain human activities--such as damming rivers and clear-cutting forests
Temperature
If temperature increases or decreases drastically (even more-so than the already drastic-temperatured environment), all of the organisms in a population are affected the same exact way. Whether the population consist of large and dense numbers or small and sparse ones, the organisms will all be affected.
Weather
If there is a huge storm, (most likely a sand-storm), all organisms will be affected. All density-independent limiting factors are essentially the same idea: an event occurs that affect all organisms equally no matter the size or density.
