a) Definition:
A density-dependent factor is one where the effect of the factor on the size of the population depends upon the original density or size of the population. A disease is a good example of a density-dependent factor. If a population is dense and the individuals live close together, then each individual will have a higher probability of catching the disease than if the individuals had been living farther apart. Not only will a greater number of individuals be affected, but, more importantly, a greater proportion of the population will be affected if they are living close together. For example, bird populations are often regulated more by this type of regulation.
b) Characteristic of the factor:
In general, density-dependent factors are biological factors, such as diseases, parasites, competition, and predation.

What kind of limiting factor depends on the population size?

Are seasonal cycles a density- dependent limiting factor.?
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.

Parasitism
Are season cycles a density- dependent factor?
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.
What is difference between density independent and density dependent limiting factors?
A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my Biology book.
What is the main difference between a density dependent limiting factor and a density independent limiting factor?
A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.

Food availability for the moose and disease for the wolf
Is seasonal cycles a density dependent limiting factor?
No it is a Density independent factor- nonliving and does not depend on population size
What are 2 density dependent limiting factor?
food and living space
What are the influencing factor of wetland?
Density-dependent limiting factor: A limiting factor whose effects depend on the size of the population depend on population density. The less dense the population, the less severe the effect of the limiting factor. Examples: Predation and disease Density-independent limiting factor: A limiting factor that has the same effect on a population regardless of its population density. Examples: Natural disasters and climate
What is a density-dependent factor limiting population growth?
Parasitism
