What is carrying capacity?

• The maximum population size that an environment can sustain indefinitely

• The ability of an organism to carry its offspring

• The weight that an organism can carry

• The speed at which a population grows

A density-dependent factor is:

• a factor that affects population size in relation to the population's density

• a factor that only affects small populations

• a factor that only affects large populations
