Key Terms:

• population
• density
• dispersion
• growth rate
• reproductive potential
• exponential growth
• carrying capacity

Main Ideas:

• Each population has specific properties, including size, density, and pattern of dispersion.
• When a population has few limits to its growth, it may have an exponential growth.  This is fastest possible growth rate of the population.
• When a population has few limits to its growth, it may have an exponential growth rate.  Usually, population growth is limited by factors such as disease and competition.
• Carrying capacity is the maximum population a habitat can support over a long period of time.
• A population that grows rapidly may be subject to density-dependent regulation.
