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 an example of a density independent resistance factor?
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.
Which of the following would be an example of a density independent factor?
Factors include:
food availability
, predator density and disease risk. 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.
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.
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 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’s the difference between density dependent and independent factor?
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.
Which one is the density independent factor?
There are many common density independent factors, such as
temperature, natural disasters, and the level of oxygen in the atmosphere
. These factors apply to all individuals in a population, regardless of the density.
Why is disease considered density-dependent?
Density-dependent factors are sometimes called
regulating factors because of their potential for maintaining population density within a narrow range of values
. … For example, disease transmission may decline as individuals perish and surviving members of a population come into contact with one another less frequently.
Can you identify which factors are density-dependent and which are density independent?
Density-dependent regulation can be affected by factors that
affect birth and death rates such as competition and predation
. Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions such as fire.
Which is not a density-dependent factor?
The correct answer is
Flooding
. A density-dependent, growth limiting factors are of four types.
Which of these is an example of a density-dependent limiting factor?
Density-dependent limiting factors include
competition
, predation, herbivory, parasitism and disease, and stress from overcrowding. Competition is a density-dependent limiting factor. The more individuals living in an area, the sooner they use up the available resources.
What is density of a population?
Population density is
the concentration of individuals within a species in a specific geographic locale
. Population density data can be used to quantify demographic information and to assess relationships with ecosystems, human health, and infrastructure.
Which of the following is a density independent factor group of answer choices?
Question Answer | what is a density-independent limiting factor? earthquake | what density-dependent factor other than the predator/prey relationship affected the populations of moose and wolves on Isle Royale? food availability for the moose and disease for the wolf |
---|
Is pollution a density independent factor?
All forms of
pollution can act as density-independent factors
. Once a pollutant enters the environment, it can have an effect on all organisms living there. It doesn’t matter if the populations are large or small – in either scenario, they can be affected negatively by the pollution.
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. As humans become denser on this planet, we will need to develop ways to generate more food in less area to overcome this density dependent factor.
