Density Dependent Factors. Increasing population size reduces available resources limiting population growth. In restricting population growth, a density-dependent factor intensifies as the population size increases, affecting each individual more strongly. Population growth declines because of Death Rate increase, Birth Rate decrease or both. There is a reduction in the food supply which restricts reproduction resulting in less offspring. The competition for space to establish territories is a behavioral mechanism that may restrict population growth. Predators concentrate in areas where there is a high concentration of prey. As long as the Natural Resources are available, in sufficient quantity, the population will remain constant. As the population decreases so do the predators. The accumulation of toxic wastes may also limit the size of a population. Intrinsic factors may play a role in limiting a populations size. High densities may cause stress syndromes resulting in hormonal changes that may delay the onset of reproduction. Immune disorders are also reported to be related to stress in high densely populated areas.
Density-Independent Factors. Weather, climate, and natural disasters such as freezes, seasonal changes, hurricanes, and fires are examples. These factors are unrelated to population size and affect everyone in the population regardless of population size.
Based on the list all are density dependent.
Any natural disaster would be a "density-independent" factor. The effect would not be directly determined by the size of the population.
These factors would also include long-term changes in the environment (temperature, precipitation).
Natural disasters,seasonal cycles,and human activity such as rivers that rush.

Food supplies can be one limiting factor.
The biggest limiting factor to attending college are high tuitions.One limiting factor in the high jump is the height of the participant.Her weight became a limiting factor when the photographer wanted a thin model.
One limiting factor in bird populations is cats.
Density-dependent limiting factor: A limiting factor whose effects depend on the size of the population depend on population density. The less dense the population, the less severe the effect of the limiting factor. Examples: Predation and disease Density-independent limiting factor: A limiting factor that has the same effect on a population regardless of its population density. Examples: Natural disasters and climate
A limiting factor is anything that restricts the amount of certain species that can live in an area. Some examples are lack of food and water, living space and available mates.

major limited factor for plant growth can be phosphorus and light.
Limiting factor
A limiting factor limits the development or growth of a population, an organism or process. Examples include: shortage of skilled labor and materials, limited labor hours and machine hours.
A limiting factor is anything that restricts the number of individuals in a population
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.
