Which of the following is a density independent factor limiting population growth?
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 are some density independent limiting factors?
The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution. The chances of dying from any of these limiting factors don't depend on how many individuals are in the population.
Which of the following could be considered a density dependent limiting factor?
Density-Dependent limiting factors include competition predation herbivory parasitism disease and stress from overcrowding.
Which of the following would be considered a density independent factor that limits population growth quizlet?
Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.
What are examples of density independent?
The two examples of density independent factors are natural disasters and human activity. Natural disasters, like wildfires, are factors that limit population sizes irrespective to density of the population.
Which is an example of a density independent population control?
Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires. Limiting factors of different kinds can interact in complex ways to produce various patterns of population growth.
What is density independent examples?
There are many common density independent factors, such as temperature, natural disasters, and the level of oxygen in the atmosphere. These factors apply to all individuals in a population, regardless of the density.
What is a density-dependent limiting factor quizlet?
Density Dependant Factors: a limiting factor of a population wherein large, large dense populations are more affected than small, less crowded ones ex. predation, competition, food supply.
Is a density independent factor that influences population growth quizlet?
Density-independent factors are environmental factors that affect the size of a population but are not influenced by changes in population density. Examples of density-independent factors that affect population growth include random weather events, such as blizzards, hurricanes and fires.
Which of the following is an example of a density independent limitation on a population quizlet?
Explanation. A density-independent limiting factor includes natural disaster such as earthquakes. The effect of an earthquake has changed the human population in the affected area.
What is density independent growth?
Density-independent growth: At times, populations invade new habitats that contain abundant resources. For a while at least, these populations can grow rapidly because the initial number of individuals is small and there is no competition for resources.
Is human population density dependent?
In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases.
What is density-dependent population growth?
Density-dependent growth: In a population that is already established, resources begin to become scarce, and competition starts to play a role. We refer to the maximum number of individuals that a habitat can sustain as the carrying capacity of that population.
What is a density independent factor?
density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area).
What is a density independent limiting factor quizlet?
density- independent. any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population. An example of such a factor is an earthquake, which will kill all members of the population regardless of whether the population is small or large.
Which limiting factor is density-independent quizlet?
Which of the following is a density-independent limiting factor? Resource shortages triggered by increasing population size are density-independent limiting factors.
Which of the following is an example of a density-independent effect on population growth?
Examples of density-independent factors that affect population growth include random weather events, such as blizzards, hurricanes and fires.
Is a density-independent factor that influences population growth quizlet?
Density-independent factors are environmental factors that affect the size of a population but are not influenced by changes in population density. Examples of density-independent factors that affect population growth include random weather events, such as blizzards, hurricanes and fires.
Which is an example of a density-independent factor quizlet?
A density-independent factor is one where the effect of the factor on the size of the population is independent of and does NOT depend upon the original density or size of the population. The effect of weather is an example of a density-independent factor.
What are the 4 density-dependent factors?
Density-dependent factors include competition, predation, parasitism and disease.
What is density-dependent and independent factors?
Summary: 1. Density dependent factors are those that regulate the growth of a population depending on its density while density independent factors are those that regulate population growth without depending on its density.
Which is an example of a density independent factor on a population quizlet?
A density-independent factor is one where the effect of the factor on the size of the population is independent of and does NOT depend upon the original density or size of the population. The effect of weather is an example of a density-independent factor.
What is example of density independent?
The two examples of density independent factors are natural disasters and human activity. Natural disasters, like wildfires, are factors that limit population sizes irrespective to density of the population.

Which of the following is an example of a density-independent limitation on a population quizlet?
Explanation. A density-independent limiting factor includes natural disaster such as earthquakes. The effect of an earthquake has changed the human population in the affected area.
What are 5 density-dependent limiting factors?
Density-dependent limiting factors
- Competition within the population. When a population reaches a high density, there are more individuals trying to use the same quantity of resources. …
- Predation. …
- Disease and parasites. …
- Waste accumulation.
What are density-dependent and independent limiting factors?
Density-dependent factors have varying impacts according to population size. Different species populations in the same ecosystem will be affected differently. Factors include: food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size.
