Based on the causal structural signal established in the sentence, complete the sentence by filling in the blank with an appropriate transition word that accurately captures the logical cause-and-effect relationship.
Answer:In evolutionary ecology, the sudden extinction of a dominant apex predator frequently destabilizes the lower trophic levels of an ecosystem; 【consequently】, herbivore populations expand rapidly without natural constraint, precipitating widespread vegetation depletion across the region.
Answer
The blank requires a causal transition word indicating that the second clause is a direct outcome of the first. Appropriate responses include words such as 'consequently', 'accordingly', 'therefore', 'thus', or 'hence'.
The correct answer must be a causal transition word (such as 'consequently', 'accordingly', or 'therefore') because the second clause specifies the direct biological outcome of the predator extinction described in the first clause. The semicolon followed by the blank requires a structural signal that introduces the logical result.
