Which is a less prone trait to extinction?

“Low trophic status” for which is a less prone trait to extinction. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Human-driven habitat conversion, exploitation, introduced enemies, pollution, and climate change often interact rather than acting independently. Traits such as slow reproduction or ecological specialization can magnify vulnerability. The remaining alternatives—“High homozygosity”, “Small population size”, “High variability”—refer to different states, processes, or scales and therefo

SUCCESSION

Which is NOT a feature of early successional species?

Early-successional species are typically selected for rapid occupation of recently disturbed, well-lit habitats. They often produce many small, widely dispersed seeds, germinate quickly, grow rapidly, mature early, and complete relatively short life cycles. Shade intolerance is common because their high photosynthetic capacity performs best in open conditions, while dense later canopies suppress them. Slow growth therefore conflicts with the standard pioneer syndrome and is more characteristic of many late-successional species that conserve resources, tolerate shade, and invest in long-lived t
