What is density dependent resistance factors?

What is density dependent resistance factors?

Density dependent factors include the environmental resources needed by the individuals of a population. Density dependent factors are referred to as Environmental Resistance Factors that determine the Carrying Capacity of the environment for a population.

What is a density dependent variable?

Typically, density dependent factors are biological factors used by the population as a resource. These can be things like food, shelter, or other limited resources. Density dependent factors cause variable changes in the population as its density changes.

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.

Why is food a density-dependent factor?

Density dependent factors typically involve biotic factors, such as the availability of food, parasitism, predation, disease, and migration. As the population increases, food become scarce, infectious diseases can spread easily, and many of its members emigrate. Compare: Density Independent Factor.

Why is food a density dependent factor?

What are density dependent three examples?

Which is not density-dependent 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).

What are three density independent factors?

Density independent factors vary depending on the population, but always affect the population the same regardless of its size. 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.

Which limiting factor is density independent?

The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution.

What factors affect density?

Temperature and pressure are two factors that can affect an object’s density. Almost all materials become less dense as they get hotter due to their particles moving around more taking up more space. Likewise, when materials cool down they tend to become denser.

What are examples of density – independent limiting factor?

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.
