What are some density independent factors that control population growth?

∙ 10y ago
a. Climate, weather (including droughts and floods), and fires can cause massive mortality in local populations irrespective of their densities.
b. Pesticide use, pollutant release, and over hunting and fishing by people can have similar effects.
c. Some species have evolved means of limiting their losses, such as seasonally migrating to a better climate or entering a period of dormancy when conditions deteriorate.
d. predators kill prey and help control populatione. Unusual weather also helps to control species like hurricanes, forest fires, ect.

∙ 13y agoNatural disasters (hurricanes, floods, volcanoes) and changes in climate are density-independent factors because the size of the population does not directly determine the effect of the factor.
Density-dependent factors include intra-species competition for resources, as well as reproduction rates, migration, predation, and parasitism.

What are the examples sentence of density independent factors?
When the population of similar animals increase in habitats the amount of recources become limited
Example of density dependent factor?
predation, availability of food, disease, parasitism Things that depend on the size of the population, as opposed to density independent factors such as weather, and natural disasters.
What are examples of density dependent factors?
Density-dependent factors are factors that limit population growth such as, a natural disaster, disease, drought, fire, etc.May I add, food supply also falls under the density-dependent factor that involves population growth. When this happens, population does not level off but usually plunges down. In the factor of disease, an example would be the Great Black Plegue in England. It wiped out many people in just weeks.
What is dependent factors?
Space and food sources are density-dependent factors.
Factors that distort the way the independent variable affects the dependent variable are referred to as?
The factors that distort the way the independent variable affects the dependent variable are referred to as the double-blinds. The factors try to explore the relationship between the dependent and independent variables.
What is the difference between density-dependent factors and density independent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
What is the difference between density independent factors and density dependent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
What type of factors are limiting factors whose effects are not influenced by population density?
density independent.
This is a limiting factor of a population that does not depend on the population density. These factors are usually abiotic factors.?
density independent limiting factor
What factor affects the same percentage of a population regardless of the population's density?
Density independent limiting affects the same percentage of a population regardless of the populations density. Density independent limiting factors are environmental factors that affect a population no matter the size.
What are the similarities between density-dependent factors and density- independent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
Limiting factors that are not controlled by the size of a population?
Density- independent factors :D
Identify density-independent limiting factors and explain how they affect a population.?
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.
What factors affecting population growth is density independent?
Predation
What is a density independent factors controlling a population?
These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
What is a density independent regulatory factor?
A density-independent regulatory factor is an environmental factor that influences population size or growth without being affected by the population density. These factors can include natural disasters like floods or droughts, temperature changes, or other abiotic factors. They have the same effect on population size regardless of the population's density.
What density independent and density dependent limiting factors may prevent the human population from continued growth?
KKK
