What is an example of density-dependent limiting 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. Mountain chickadees (Parus gambeli) compete for a special kind of nest site—tree holes.
What are 4 examples of density-dependent factors?
Density-dependent factors include competition, predation, parasitism and disease.
What are 5 density-dependent limiting factors?
Density-dependent limiting factors include competition, predation, herbivory, parasitism and disease, and stress from overcrowding.
What human activities are examples of density independent limiting factors?
Bio. Ch. 5.2

| Give examples of density-independent limiting factors in a population. | Natural disasters can cause a sudden decline in population, as can human activities (damming a river; over-cutting a forest); unusual weather; seasonal cycles. |
Is earthquake density dependent?
density-independent factor 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.
What are density dependent limiting factors 6 examples?
Density-dependent limiting factors
- Competition within the population. When a population reaches a high density, there are more individuals trying to use the same quantity of resources.
- Predation.
- Disease and parasites.
- Waste accumulation.
What are density-dependent limiting factors 6 examples?
What are the 3 density-dependent limiting factors?
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
Is earthquake density-dependent?
What are two examples of density dependent factors that affect population growth What are two examples of density independent factors?
Examples of density dependent factors are food, shelter, predation, competition, and diseases while examples of density independent factors are natural calamities like floods, fires, tornados, droughts, extreme temperatures, and the disturbance of the habitat of living organisms.
What are density dependent three examples?
Some common examples of density-dependent limiting factors include:
- Competition within the population. When a population reaches a high density, there are more individuals trying to use the same quantity of resources.
- Predation.
- Disease and parasites.
- Waste accumulation.
What are four density dependent limited factors?
Competition within the population. When a population reaches a high density,there are more individuals trying to use the same quantity of resources.
What are examples of limiting factors?
Examples of Limiting Factors. Resources. Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.
What is density dependant and independent factors?
Density Dependent is responsible for regulating the population in proportion to its density such as prediction,competition,or disease.
When do density dependent factors operate most strong?
Density-dependent factors operate only when the population density reaches a certain level. These factors operate most strongly when a population is large and dense. They do not affect small, scattered populations as greatly.
