What are 4 examples of density dependent factors?

Some common examples of density-dependent limiting factors include:
  • 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.

Which is a density dependent factor quizlet?

Density-dependent factors: competition, predation, parasitism, and disease. Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.

What are 5 density dependent limiting factors?

Density-dependent limiting factors include competition, predation, herbivory, parasitism and disease, and stress from overcrowding.

What is a density dependent factor What is a density-independent factor?

Density-dependent factors have varying impacts according to population size. … Density-independent factors are not influenced by a species population size. All species populations in the same ecosystem will be similarly affected, regardless of population size. Factors include: weather, climate and natural disasters.

Which is a density independent factor answers?

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 of the following are examples of density-dependent factors quizlet?

In general, density-dependent factors are biological factors, such as diseases, parasites, competition, and predation. 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.

What are three density-dependent factors?

Density-dependent factors include competition, predation, parasitism and disease.

Is hunting a density-dependent factor?

Predation: The Balance of Hunter & Hunted

In some cases imbalances in predator-prey relationships create density-dependent limiting factors.

Which of the following is an example of density independent factor?

Most density-independent factors are abiotic, or nonliving. Some commonly used examples include temperature, floods, and pollution.

What is density factor?

Density Factor is a zoning term for the maximum allowable number of residential units one can develop on a property. The allowable residential square footage of the building is divided by the density factor to determine the allowable number of units. These factors vary in different zoning districts.

Which of the following is an abiotic density-dependent factor?

Density Dependent Factors

Some abiotic limiting factors affect members of a population because of the population density. These things include disease, food supply, and increased predation.

Which of the following is a density independent factor quizlet?

Density Independent Factors: unrelated to population size ex. natural disaster, hurricane, tornado, flood. 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.

Which of the following is an example of a density-dependent limiting factor *?

Density-dependent limiting factors tend to be biotic—having to do with living organisms. Competition and predation are two important examples of density-dependent factors.

Is food a density dependent factor?

For many organisms, food is a density dependent factor. At low densities, food is almost always readily available. At high densities, it becomes scarce.

Which of these is a density dependent factor apex?

Density-dependent factors include competition, predation, parasitism and disease.

Is a drought a density independent factor?

Density-independent limiting factors affect all populations in similar ways, regardless of population size and density. Unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires, can act as density-independent limiting factors.

Which are density independent factors?

Density independent factors, in ecology, refer to any influences on a population’s birth or death rates, regardless of the population density. Density independent factors are typically a physical factor of the environment, unrelated to the size of the population in question.

Is density-dependent or independent?

Density Dependent is responsible for regulating the population in proportion to its density such as prediction, competition, or disease. Density Independent are those that regulate the population without considering its density such as natural disasters and the weather.
