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? Competition for resources increases mortality rates. Delayed reproduction yields larger litter sizes but reduces the net reproductive effort of an individual because o f decreased likelihood of survival of offspring. Larger sized litters of offspring have individuals with smaller body sizes. Delayed reproduction yields smaller litter sizes and reduces the net reproductive effort o f an individual but increases the likelihood of survival of offspring. Delayed reproduction increases the likelihood o f parent mortality prior to reproducing due to an environmental event. Which of the following is not true? The Hardy-Weinberg Principle states that sexual reproduction doesn't cause evolution. Females that delay reproduction tend to have fewer and larger offspring. Population density and patch size explain dispersal of populations. Intersexual selection involves competition between the same individuals of the same sex. whereas intersexual selection involves competition between individuals of the opposite sex. Which o f the following is true? Metapopulations are based on the balance between habitat availability- and suitability. Exploitation competition occurs when access to a resource is limited by the presence of a competitor. Populations with higher resource availabilities are not expected to have higher survival given an extreme environmental event. In general, there is a negative relationship between an organism's body size and its home range. Density-dependence and density independence do not co-occur in populations.
