Population: definition

• a group of organisms belonging to different species that live in a particular area

Population Density: definition

• calculated by dividing the number of individuals in a population by the unit area

• calculated by dividing the number of different populations by the unit area

• calculated by dividing the number of individuals in a community by the unit area

• calculated by dividing the number of individuals in an ecosystem by the unit area

Density Independent Factor: definition

• population changing factors that occur regardless of how dense the population is

• population changing factors that occur in very dense populations

Carrying Capacity: definition

• the maximum number of individuals a Popeye's can support

• the average number of individuals an environment can support

• the minimum number of individuals an environment can support

• the maximum number of individuals an environment can support

Primary Succession
