Question

The rate of infant mortality in a K-selected population is likely to be

a. higher than in r-selected populations.

b. lower than in r-selected populations.

c. similar to rates in r-selected populations.

d. unrelated to population density.

Answer 1

B). lower than in r-selected populations.

Typically, r-selected species exploit empty niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood. In contrast, K-selected species are strong competitors in crowded niches, and invest more heavily in many fewer offspring, each of which has a relatively high probability of surviving to adulthood.
