Population Density & Dispersion

A population's carrying capacity is defined as...

• Maximum number of individuals the population can support before growth starts to rapidly expand

• Maximum number of individuals in the population the available resources can support before growth is halted

• Maximum number of individuals the population's resources can support before growth is stopped, and starts to rapidly decline

• Minimum number of individuals needed to get a population off the ground to begin growing exponentially

Emigration is

• the movement out of an area

• the movement into an area

• movement in and out of an area

• migration

The way in which individuals of a population are spread out is called

• population density
• survivorship
• population dispersion
• logistic curve

The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time -

• Clumped dispersion

• Uniform dispersion

• Random dispersion
