Drought is considered a density-independent limiting factor because its impact on a population is not directly related to the population size. Drought affects all individuals in an area regardless of their density, leading to decreased resources like water and food which can limit population growth or survival. This contrasts with density-dependent factors, which have a stronger impact on populations as they become more crowded.

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.
A limiting factor for a predator species could be a decrease in prey population, which would reduce the predator's food source. Additionally, competition with other predator species for the same prey can also be a limiting factor. Environmental factors such as habitat loss or degradation could further impact the predator's ability to thrive.
In science, a limiting factor refers to a factor that constrains the growth of a population or the productivity of a system. This factor can be environmental, such as food availability or temperature, and when it becomes scarce, it limits the organism's ability to thrive. Identifying and understanding limiting factors is important in ecological studies and resource management.
A drought can directly affect limiting factors such as water availability, soil moisture, and plant growth. Reduced rainfall leads to less water for plants and animals, resulting in decreased food sources and habitat. The lack of water also impacts agricultural productivity and can contribute to water scarcity for human populations.
Food availability is typically the limiting factor for squirrels, as they need to constantly forage for nuts, seeds, fruits, and other food sources. Competition with other squirrels or predators can also be limiting factors for their population.
