Which one of the following organisms best illustrates K-selection?
A) the production of thousands of eggs every spring by frogs
B) mice that produce three litters of 10-15 babies in the course of a summer
C) a polar bear producing one or two cubs every three years
D) a species of weed that quickly spreads into a region of cleared trees
E) All of the choices are examples of K-selection.
Which one of the following organisms best illustrates K-selection?
K-selected type organisms are similar to humans, which dedicate more time to survival and food gathering over reproduction.
Because choices A, B, and D show the effects of fast growing populations, only choice C (involving polar bears) illustrates K-selection.
