Which is a density independent factor in controlling a population
What are the factors of density independent?
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 an example of a density independent factor on a population?
Examples of Density-Independent Factors
Some commonly used examples include temperature, floods, and pollution. How could temperature be a factor in determining the density of a population?
Which is an example of a density independent population control?
For example, for most organisms that breathe oxygen, oxygen availability is a density-independent factor; if oxygen concentrations decline or breathable oxygen is suddenly made unavailable, such as when oxygen-using plants are covered by rising floodwaters, those organisms perish and populations of the various affected …
Which factor is density independent quizlet?
Terms in this set (4)
Density-dependent factors: competition, predation, parasitism, and disease. Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.
What is density independent population 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. ΔN is the change in number. …
What are 4 examples of 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.
What is an example of a density dependent 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.
Which of these is a density independent factor apex?
What is a density independent factor apex? The density independent factor in controlling a population is C. Floods. Shortage of food and diseases are all density dependent factors.
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.
What are 5 density-dependent limiting factors?
Density-dependent limiting factors include competition, predation, herbivory, parasitism and disease, and stress from overcrowding.
Is drought density-dependent or independent?
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 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.
How density-dependent and density independent factors regulate population growth?
Density-dependent limiting factors cause a population’s per capita growth rate to change—typically, to drop—with increasing population density. … Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.
Which of the following is a density independent factor limiting human population?
Which of the following is a density-independent limiting factor? Resource shortages triggered by increasing population size are density-independent limiting factors.
Is deforestation a density independent factor?
Density dependent limiting factors such as decreased availability of space due to deforestation is a global issue, causing decline and extinctions in many populations.
What is density-dependent population regulation?
In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population. … Usually, the denser a population is, the greater its mortality rate.
Which of the following is an example of a density independent limitation on a population quizlet?
Density-INDEPENDENT limiting factors such as: unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires. competition, predation, herbivory, parasitism, disease, and stress from overcrowding.
Are dams density dependent or density independent limiting factors?
Answer: Dams are density – independent .
