Question 14.16

Ecology is best defined as the study of:

  • a) the relationships between all living organisms and their environments.
  • b) the relationships between parasites and their hosts.
  • c) aquatic organisms.

  • e) the preservation of habitats.

Question 14.17

On average, does a pair of elephants or a pair of rabbits leave more offspring that survive to become adults and reproduce?

  • a) The pair of elephants, because elephants live much longer and have more breeding seasons.
  • b) The pair of rabbits, because they have so many more offspring per breeding season than do elephants.
  • c) The pair of rabbits, because they reach sexual maturity more rapidly.
  • d) The pair of elephants, because any individual elephant that is born is more likely to survive to become an adult and reproduce.
  • e) If both populations are stable, the pair of elephants and the pair of rabbits will leave the same number of offspring that survive to become adults and reproduce.

Question 14.18

In a population exhibiting logistic growth, the rate of population growth is greatest when N is:

  • a) 0.5 K.
  • b) 0.
  • c) above the carrying capacity.
  • d) K.
  • e) All of the above are correct; the rate of population growth is constant in logistic growth.
