Practice question

“Chaparral” for which biome is characterized by sclerophyllous vegetation. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Terrestrial biomes are distinguished primarily by long-term temperature and precipitation regimes, their seasonality, and the vegetation physiognomy those conditions support. Latitude is informative only because it often covaries with climate. The remaining alternatives—“Savanna”, “Tundra”, “Taiga”—refer to different states, processes, or scales and therefore do not express the same causal relationship. Plant growth form integrates water balance, fire, frost, nutrient availability, and growing-season length. Animals respond to the same filters through migration, dormancy, thermoregulation, and dietary specialization. Linking the wording to measurable consequences for fitness, abundance, or flux gives the conclusion its scientific meaning and prevents a purely mnemonic interpretation. Field observations could test this account by measuring the proposed driver and the demographic or ecosystem response while controlling plausible confounding factors.
