Each category has one definition and two examples.
Definition: limiting factor that affects all populations in similar ways, regardless of population size
Example: Climate extremes (monsoons or earthquakes)
Example: Food or nutrient limitation
Example: Predation and Competition
Example: Diseases
Definition: a factor that limits a population more as population density increases
