Which is a density independent factor in controlling population apex?

Which is a density independent factor in controlling a population? Answer: Density-independent factors such as weather and climate exert their influences on population size regardless of the population's density. In contrast the effects of density-dependent factors intensify as the population increases in size.

Which is a density-dependent factor in controlling a population?

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 are density independent factors in a population?

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 an example of a density independent control on a population?

Density-independent limiting factors As an example, let's consider a wildfire that breaks out in a forest where deer live. The fire will kill any unlucky deer that are present, regardless of population size. An individual deer's chance of dying doesn't depend at all on how many other deer are around.

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.

Is predation a density independent factor?

(3) Predation is a density-dependent factor that slows population growth by increasing death rates due to more individual organisms being preyed upon. (4) Competition for natural resources is also a density-dependent factor that limits population growth by either increasing death rates or decreasing birth rates.

Which is a density-independent factor quizlet?

Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.

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.

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 an example of density independent factor quizlet?

Density independent factors can affect a population no matter what its density is. For example: natural disasters, temperature, sunlight, human activities, physical characteristics and behaviors of organisms affect any and all populations regardless of their densities.

What human activities are examples of density-independent limiting factors?

Density-Independent Limiting Factors Some limiting factors do not necessarily depend on population size. Density-independent limiting factors depend on population density, or the number of organisms per unit area. Examples include severe weather, natural disasters, and human activities.

Which is a density-dependent factor quizlet?

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

Is parasitism a density-dependent factor?

Parasitism and disease are density-dependent effects, because the denser the host population, the more easily parasites can spread from one host to another.

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.

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

The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution.

Which factor is density-independent quizlet?

Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.

What are 3 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.

What is a density independent 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. habitat.

Which of the following are density independent factors quizlet?

Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.

Is predation density-dependent or independent?

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.

Which is an example of a density-independent factor quizlet?

Which factor is a density-independent limiting factor quizlet?

Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.

What is an example of a density independent factor on a population quizlet?

The effect of weather is an example of a density-independent factor. A severe storm and flood coming through an area can just as easily wipe out a large population as a small one. Another example would be a harmful pollutant put into the environment, e.g., a stream.

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

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

What are 5 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 is a density independent limiting factor except?

Chapter 5 Study Guide Biology Crisp

Question	Answer
a limiting nutrient is to ecosystem productivity as a limiting factor is to population	growth rate
each of the following is a density-dependent limiting factor except (competition,seasonal cycles,crowding,disease)	seasonal cycles

What human activities are examples of density independent limiting factors?

Which is an example of density independent limiting factor?

The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution.

Which of these is an example of a density independent factor?

These include competition, predation, availability of food, presence of diseases, etc. On the other hand, the factors that affect the population size irrespective of its density are called density-independent factors. These include climatic conditions, catastrophic factors such as fire, tsunami, etc.
