REVIEW & REHEARSE: 14 POPULATION ECOLOGY
Q
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.
- d) interactions between predator and prey populations.
- e) the preservation of habitats.
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.
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.
