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.

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.
Density-dependent limiting factors, such as competition for resources, predation, disease, and parasitism, depend on the population size. As the population size increases, the impact of these factors may also increase, leading to adjustments in population growth and dynamics.
Seasonal cycles can impact population dynamics, but they are not considered a density-dependent limiting factor. Density-dependent factors depend on the population size, such as competition for resources or predation. Seasonal cycles can affect populations through environmental changes like temperature or precipitation variations.
A density dependent factor is for example, lower birth rate because there isn't enough food in a certain place. A density independent factor is an earthquake or fire, something that will happen regardless of how many organisms there are.
Space and food sources are density-dependent factors.

Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.

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.

Yes, seasonal cycles can be considered a form of density-dependent limiting factor. As populations increase during certain seasons, resources may become more limited, impacting population growth and survival. This dependence on population density for resource availability is a key characteristic of density-dependent factors.
