Module 4 Test review

No population can grow indefinitely. The ultimate size of any population is limited by

• the carrying capacity of its environment.

• its death rate

• its birth rate

• its r value

Which of these factors increases the size of a population?

• birthrate

• emigration

• death rate

• carrying capacity

Which factor would most likely be an example of a density-independent factor that limits population growth?

• disease

• food availability

• daily temperature extremes

• parasites

Which scenario best illustrates the concept of carrying capacity?

• The exponential growth of a fruit fly population continues to increase and will eventually double in ten days.

• The exponential growth of ants increases dramatically when its competitor species is forced to move due to habitat loss.

• The logistic growth of a giraffe population continues to decline due to the increase in number of predators.

• The logistic growth of a bunny population has stabilized because the population has reached the largest numbers that the area can support.
