CH 5 Population Review

The number of individuals per unit area is:

• population density

• carrying capacity

• limiting factor

The largest number of individuals of a population that a given environment can support is:

• population density

• carrying capacity

• limiting factor

A factor that causes the growth of a population to slow or decrease:

• population density

• carrying capacity

• limiting factor

Movement of individuals into an area occupied by an existing population:

• immigration

• emigration

• exponential growth

• logistic growth

Movement of individuals out of an area occupied by an existing population:

• immigration

• emigration

• exponential growth

• logistic growth

Pattern in which the individuals in a population reproduce at a constant rate

• immigration

• emigration

• exponential growth

• logistic growth

Pattern in which a population's growth rate slows or stops following a period of exponential growth:

• immigration

• emigration

• exponential growth

• logistic growth

Examples of density-dependent limiting factors:

• Competition, predation, food availability, disease, parasitism

• Hurricane, earthquake, drought, wildfires, natural disasters

Examples of density-independent limiting factors:

• Competition, predation, food availability, disease, parasitism

• Hurricane, earthquake, drought, wildfires, natural disasters

This affects all populations in similar ways, regardless of population size:

• Density-dependent limiting factor

• Density-independent limiting factor
