Which risk increases in small mammals when interruption of torpor cycles occurs?

💡 Explanation

Torpor arousal requires significant energy expenditure using thermogenesis by brown fat; continuous cycling depletes lipid stores because sufficient time for metabolic repletion is unavailable; therefore, depleted energy reserves are the risk, rather than cardiac strain or increased glucose.
