What would be a good example of a density independent factor?
Most density-independent factors are abiotic, or nonliving. Some commonly used examples include temperature, floods, and pollution. How could temperature be a factor in determining the density of a population? Imagine a heavily forested area that is home to a population of mosquitoes.
Which 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).
Which of the following is not an example of density dependent?
Explanation: Density-dependent factors are the factors that have varied or different effects as per the population size. In other words, the factors that are not influenced by the density of the population is density-dependent factors. These factors include competition, disease, and predation.
Which of the following is an example of a density dependent factor quizlet?
A disease is a good example of a density-dependent factor. If a population is dense and the individuals live close together, then each individual will have a higher probability of catching the disease than if the individuals had been living farther apart.
Which factors are used to calculate population growth?
Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Which type of limiting factor affects a large?
The density dependent limiting factor is the factor which affects the population on the basis of the density. For example, the effect of the disease will be more profound if the population is large, but in small populations few members will get infected.
Which factor does not affect the size of a population?
Unlike the gain or loss of member through immigration, emigration, or death, the age of a population’s members does not effect population size, meaning the correct answer is D.
What are the three main factors that determine population growth?
Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration.
What are the three factors that can affect population size quizlet?
Terms in this set (6)
- death rate. mortality; number of deaths within a population per unit of time.
- birthrate. natality; number increases at which reproduction increases population (birth/unit of time)
- Immigration.
- emigration.
- Four rates used to calculate population change.
- growthrate.
Which factors affect a population’s growth regardless of the population size?
Factors that affect the growth of a population, regardless the population size, are known as density-independent limiting factors as these factors limit the population growth, regardless the density of a population. These factors include climatic conditions, natural disasters, human activities, and sunlight.
What factors can influence how populations change over time quizlet?
The factors that can affect population size are the birthrate, death rate, and the rate at which individuals enter or leave the population. A population can grow when its birthrate is higher than its death rate.
What type of population growth is affected by carrying capacity quizlet?
logistic growth
What type of population growth is affected by carrying capacity?
logistic curve
What happens when a population overshoots its carrying capacity quizlet?
when a population grows beyond its carrying capacity; Die-offs often occur when a population overshoots its carrying capacity. You just studied 66 terms!
What is carrying capacity and how does it affect the size of a population?
Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
What happens when carrying capacity is exceeded?
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
How do you determine the carrying capacity of a population?
Carrying capacity is most often presented in ecology textbooks as the constant K in the logistic population growth equation, derived and named by Pierre Verhulst in 1838, and rediscovered and published independently by Raymond Pearl and Lowell Reed in 1920:Nt=K1+ea−rtintegral formdNdt=rNK−NKdifferential formwhere N is …
