Earthquakes causes death of organisms despite the numbers present in the population. Hence it is an density independent factor.
The impact of the earthquake is the same even if the population is 100 or 1000.
It also does not depend on whether the organisms possess traits that aid in their survival.

A population with a low population density would be least likely to be affected by a density-dependent limiting factor, as these factors typically become significant when populations reach higher densities.
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.
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
density independent limiting factor
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-independent limiting factors that may prevent human population growth include natural disasters like earthquakes or hurricanes. Density-dependent limiting factors could include limited access to resources such as food and water, which can be exacerbated as the population increases. Additionally, the spread of diseases in crowded areas can also limit human population growth.
A population size decrease is the usual response in the population size of many species to a density-independent limiting factor. Not enough food is an example of a limiting factor.
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.
Natural disasters, such as hurricanes or fires, are considered density-independent limiting factors because their impact on a population does not depend on the population's size or density. Instead, these factors affect a population regardless of its size.

Density-independent limiting factors are factors that do not rely on the population and are aspects of an environment that limit its growth like hurricanes, fires, and deforestation.
A natural disaster is considered a density-independent limiting factor because its impact on a population does not depend on the population's size or density. Events such as hurricanes, earthquakes, and wildfires can affect large areas and populations regardless of how many individuals are present. This means that even in low-density populations, a natural disaster can cause significant mortality and disruption, leading to a decline in population numbers without being influenced by the population's density.

A drought is considered a density-independent limiting factor because it affects all individuals in a population regardless of their population density. It reduces the availability of water, impacting the survival and reproduction of organisms, leading to a decline in population size.
