1) Part of some organisms’ life cycle to allow survival during a period when the costs of continued normal metabolic activity would be too high a) photosynthesis b) dormancy c) fermentation d) reciprocal altruism 2) Dormancy which occurs before the onset of adverse conditions. a) consequential b) predictive 3) Dormancy which occurs after the onset of adverse conditions. a) consequential b) predictive 4) Conditions under which mammals will hibernate. a) Drought b) Low temperatures c) High temperatures d) Lack of food 5) Conditions under which animals will undergo aestivation. a) Drought b) Low temperatures c) High rainfall d) Lack of food 6) During dormancy there is a a) decrease in metabolic rate b) increase in heart rate c) increase in body temperature d) increase in breathing rate 7) A period of reduced activity in some animals with high metabolic rates is... a) hibernation b) aestivation c) daily torpor d) migration 8) Some species of lungfish live in African lakes. If there is a drought, lakes may dry out but the lungfish can survive by burying themselves in the remaining mud and becoming dormant. Identify the type of dormancy displayed by the lungfish. a) predictive aestivation b) consequential aestivation c) predictive hibernation d) consequential hibernation 9) Dormice live in deciduous woodland. When temperatures decrease significantly they survive by rolling into a tight ball in a nest of leaves and grass and become dormant. Identify the type of dormancy displayed by the dormice. a) predictive aestivation b) consequential aestivation c) predictive hibernation d) consequential hibernation 10) The giant bullfrog of South Africa lives in a habitat in which hot and dry conditions can occur at any time of year. To survive these conditions, the frogs respond by becoming dormant. Identify the type of dormancy. a) predictive aestivation b) consequential aestivation c) predictive hibernation d) consequential hibernation
