a. Climate, weather (including droughts and floods), and fires can cause massive mortality in local populations irrespective of their densities.
b. Pesticide use, pollutant release, and over hunting and fishing by people can have similar effects.
c. Some species have evolved means of limiting their losses, such as seasonally migrating to a better climate or entering a period of dormancy when conditions deteriorate.
d. predators kill prey and help control populatione. Unusual weather also helps to control species like hurricanes, forest fires, ect.
What else can I help you with?
What are the examples sentence of density independent factors?
When the population of similar animals increase in habitats the amount of recources become limited
Example of density dependent factor?
predation, availability of food, disease, parasitism Things that depend on the size of the population, as opposed to density independent factors such as weather, and natural disasters.
What are examples of density dependent factors?
Density-dependent factors are factors that limit population growth such as, a natural disaster, disease, drought, fire, etc.May I add, food supply also falls under the density-dependent factor that involves population growth. When this happens, population does not level off but usually plunges down. In the factor of disease, an example would be the Great Black Plegue in England. It wiped out many people in just weeks.
What are factors that change and can be measure in an experiment?
Factors that can change and be measured in an experiment are known as variables. These include independent variables, which are intentionally manipulated by the researcher to observe their effect, and dependent variables, which are measured to assess the impact of changes in the independent variable. Additionally, control variables are kept constant to ensure that any observed effects can be attributed to the independent variable. Other measurable factors may include environmental conditions, time, and quantities.
What is dependent factors?
Space and food sources are density-dependent factors.
What is the difference between density independent factors and density dependent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
What is the difference between density-dependent factors and density independent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
This is a limiting factor of a population that does not depend on the population density. These factors are usually abiotic factors.?
density independent limiting factor
What are the similarities between density-dependent factors and density- independent factors?
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.
What factor affects the same percentage of a population regardless of the population's density?
Density independent limiting affects the same percentage of a population regardless of the populations density. Density independent limiting factors are environmental factors that affect a population no matter the size.
Identify density-independent limiting factors and explain how they affect a population.?
Density-independent limiting factors are factors that do not rely on the population and are aspects of an environment that limit its growth like hurricanes, fires, and deforestation.
What factors affecting population growth is density independent?
Predation
Which f the following is a density- independent limiting factor?
Natural disasters, such as hurricanes or fires, are considered density-independent limiting factors because their impact on a population does not depend on the population's size or density. Instead, these factors affect a population regardless of its size.
What are the 2 types of population regulation?
The two types of population regulation are density-dependent factors, which are influenced by population size, and density-independent factors, which affect populations regardless of size. Density-dependent factors include competition for resources, predation, and disease. Density-independent factors include natural disasters, climate events, and human activities.
Why would people use a density-independent limiting factor to control populations of introduced species?
People might use density-independent limiting factors, such as habitat modification or chemical control, to manage populations of introduced species because these methods can have a quick and direct impact on population size. They can help control invasive species that are causing harm to native ecosystems and species. Density-independent factors can be effective in reducing population levels without relying on natural predators or disease.
What are the two types of limiting factors?
The two types of limiting factors are density-dependent factors, which increase in intensity as population density increases, and density-independent factors, which affect populations regardless of their density. Examples of density-dependent factors include competition for resources and disease, while examples of density-independent factors include natural disasters and climate change.
What is a density independent factors controlling a population?
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.
