Density-dependent
limiting factors
Introduction: Population density is the number of individuals in a population per unit of area. Some limiting
factors only affect a population when its density reaches a certain level. These limiting factors are known as
density-dependent limiting factors.
Question: How does a density-dependent limiting factor affect carrying capacity?
1. Think about it: What do you think some density-dependent limiting factors might be?
2. Predict: Suppose a shopping mall is built near a rabbit warren, leaving less land available for rabbits. How
will this affect the environment's carrying capacity?
3. Experiment: Use the Gizmo to find the carrying capacity with Am

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa.which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
