Practice question

The keyed exception is “High reproductive output.” In the context of which of the following is not a feature of species prone to extinction, that statement differs from the governing ecological pattern and must be evaluated against the mechanism rather than accepted from wording alone. The mechanism should be evaluated across both local and global scales. Local disappearance can be reversed by recolonization, whereas global extinction is irreversible and requires the loss of every surviving population. The remaining alternatives—“Large body size”, “Fixed migratory route”, “Narrow distribution”—refer to different states, processes, or scales and therefore do not express the same causal relationship. 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. Field observations could test this account by measuring the proposed driver and the demographic or ecosystem response while controlling plausible confounding factors.
