How would you classify a biotic factor such as food availability that limits population size?

Density-dependent-Density-dependence in population biology refers to factors whose influence increases (or decreases) depending on the density of a population (or a number of individuals of a certain species in a set area). If a forest was populated entirely of a single species, then the intensity of the fire would indeed depend on the density of that population.

Density-independent -A device-independent (also: density-independent pixel, dip) is a physical unit of measurement based on a coordinate system held by a computer and represents an abstraction of a pixel for use by an application that an underlying system then converts to physical pixels.
