Which species likely shows all three extremes: growth, survival, fecundity?

“Elephant” for which species likely shows all three extremes: growth, survival, fecundity. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Selection favors the schedule that increases lifetime reproductive success under local mortality and resource conditions. Body size, development time, fecundity, parental investment, and generation length consequently tend to covary. The remaining alternatives—“Annual grass”, “Banana”, “None”—refer to different states, processes, or scales and therefore do not

Which trait is associated with ruderal species?

“Early reproduction” for which trait is associated with ruderal species. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Life-history traits reflect allocation among growth, maintenance, survival, and reproduction. Energy invested in many offspring cannot simultaneously be invested in large offspring, prolonged care, or future breeding, creating measurable trade-offs. The remaining alternatives—“Low growth rate”, “Long lifespan”, “Strong competition”—refer to different states, processes, or scales
