What are 3 example of a density independent factor?
Most density-independent factors are abiotic, or nonliving. Some commonly used examples include temperature, floods, and pollution.

Which of the following is a density independent limiting factor quizlet?
Which of the following is a density-independent limiting factor? Resource shortages triggered by increasing population size are density-independent limiting factors.
What is a density independent factor?
noun, plural: density independent factors. (ecology) A factor that affects the size of a population independent or regardless of the population density. Supplement. In ecology, density independent factors are the physical or abiotic factors like weather, forest fire, pollutant, etc.
What is density-dependent limiting factor?
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 are the 4 density-dependent factors?
Density-dependent factors include competition, predation, parasitism and disease.
What is a density-dependent limiting factor?
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 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.
What is the density-dependent limiting factor?
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.
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 4 examples of density-dependent limiting factors?
Density dependent limiting factor
- food and water supply – large population would require for a higher supply of food and water. …
- living space – for instance, the growth of plants is affected by competition for space. …
- predation – more prey animals could mean more predators, thus, increased predation.
What is a density independent limiting factor and give an example?
Wildfire is abiotic (nonliving), and most density-independent limiting factors fall in this category. Other density-independent factors include hurricanes, pollutants, and seasonal climate extremes. Density-dependent limiting factors tend to be biotic—having to do with living organisms.
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 is density-dependent and independent?
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.
What are 4 density-independent limiting factors?
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.
Which is a density-independent factor quizlet?
Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.
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.
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.
What are the 4 density-dependent limiting factors?
Density-dependent factors include competition, predation, parasitism and disease.
