Which o f the following best describes an ecological trade-off between fecundity

Question

Which o f the following best describes an ecological trade-off between fecundity and juvenile survival? Larger sized litters o f offspring have individuals with smaller body sizes. Delayed reproduction increases the likelihood o f parent mortality prior to reproducing due to an environmental event. Delayed reproduction yields smaller litter sizes and reduces the net reproductive effort o f an individual but increases the likelihood of survival of offspring. Competition for resources increases mortality rates. Delayed reproduction yields larger litter sizes but reduces the net reproductive effort of an individual because of decreased likelihood of survival of offspring.

Explanation / Answer

C. Delayed reproduction yields smaller litter sizes and reduces the net reproductive effort of an individual but increases the likelihood of survival of offspring

The exchange between fertility/fecundity and juvenile survival would be ensured if reproduction at a more mature age gives rise to small litters but more survival rates for the produced offspring.
