The change in population size over time is equal to the _

• Birth rate - death rate

• Birth rate x death rate

• Birth rate / death rate

_ growth is influenced by carrying capacity

• Exponential

• Logistic

• Both answers are correct

Carrying capacity is the _ number of organisms that can be supported by a population’s habitat

• Minumum

• Maximum
