#Unit 10. Ecological Principles

Density-independent factors limit population size regardless of the population’s density.

Common density-independent factors include natural disasters such as tornadoes, hurricanes, floods, and fires.

#Unit 10. Ecological Principles

Density-dependent factors affect population size in relation to the population’s density.

Density-dependent factors down into two categories.

Negative density dependence

Positive density dependence (inverse density dependence
