Quizplus · Accepted Answer

R-selection is characterized by density-independent selection, where individuals produce many offspring with low parental investment, whereas K-selection is characterized by density-dependent selection, where individuals produce few offspring with high parental investment.

Answer: C
 Iteroparity is characterized by repeated reproduction with relatively few offspring produced at each event, while semelparity is characterized by a one-shot, large reproductive effort before death.

Answer: D
 Semelparity is recorded in Pacific salmon, where individuals undergo a single reproductive event before dying.

Answer: E
 Life history traits represent trade-offs between the allocation of resources to growth, maintenance, and reproduction, often with limited resources.
