They are effective in the case of both, large populations and small populations.

Definition of density independent factors. Any factor, such as climate, that is not dependent on the density of population. At this point in your biology or ecology course, you probably heard of the term competition. Any factor that affects a population by the same percentage, regardless of density.

Individuals in a population are always competing for limited resources like food, mates, shelter, and water. Density dependent limiting factors competition. Density is defined as an object's mass per unit.

A few examples of how density applies to everyday life are in ship building, helium balloons, pipe design and the fact that ice floats on water. Definition of density dependent limiting factor competition. All species populations in the same ecosystem will be.

What is the difference between a density dependent and density independent factor? Density independent factors limit population sizes in an ecosystem due to events that occur regardless of the density of a. Density independent operates in both small and large populations.

Some things that happen to populations, such. Density is defined as the physical quantity that quantifies the distribution of mass or any other considered quality over a given volume.
