Multiple Choice
Multiple ChoiceAlthough there are organisms whose life histories fall somewhere between iteroparity and semelparity, life history always represents a trade-off. Why is this?
A
Parents always try to leave adequate resources for their offspring, so the parents may suffer.
B
In unpredictable environments, iteroparity is favored because it may require many attempts to successfully reproduce.
C
Where resource competition is intense, semelparity is favored since of the many offspring produced, only a few will survive.
D
All of the listed responses are correct.
E
The energy cost of reproduction is high, so there are not enough resources to reproduce often, produce many offspring, and take care of them.
