| Reproductive success of an organism is best measured by its | Number of offspring that survive to reproduce |
| A trade-off for having many offspring would be | That they would likely be small in size |
| Members of the California sheephead fish species begin their life as females and then become males. This is referred to as | Sequential hermaphroditism |
| Successful reproduction can result in a | Lower chance of future reproduction |
| The behavioural, physiological, and energetic activities involved in current reproduction result in | Reduced future survival, fecundity, and growth |
| Early sexual maturity is predicted to result in | Higher reproduction earlier in life |
| In long-lived species of organisms, the primary advantage of delaying reproduction (late maturity) is | Larger initial body size during the first reproduction event |
| An animal with high fecundity is predicted to have | A lower survival rate |
| Altricial young are relatively | Helpless at birth and require relatively little time for incubation and gestation (inkubation af æg og drægtighed) (In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents develop in spurts after birth). Modsat: Præocociale er arter, hvor de unge er relativt modne og bevægelige fra fødsels- eller klekkingsøjeblikket. |
| Pacific salmon migrate upstream and after breeding, soon die. They are termed? Hvad er det andet alternativ? | Semelparous. For at maksimere fitness, afbalancerer en organisme øjeblikkeligt reproduktionsindsatser mod fremtidige udsigter. Et alternativ, semelparity, er investering af maksimal energi i en enkelt reproduktionsindsats. Det andet alternativ, iteroparitet, er placeringen af mindre energi til gentagne reproduktionsindsatser. |
