Fill in the Blanks Adaptations of endotherms and plantsOnline version Complete this fill-in-the-blanks activity on the adaptations of endotherms and plants. by Belinda Schirmer 1 tolerance migration burrowing position body temperature metabolic Endotherms are organisms that rely on internal sources , such as activity , to maintain their temperature within a very narrow range of limits despite variations in the ambient . Behavioural adaptations of endotherms to maintain body temperature include changing or alignment of the body , , nocturnal activity and . 2 torpor insulation metabolic Structural countercurrent volume ears adaptations of endotherms to maintain body temperature include and surface area to ratio related to body shape and size of structures such as . Physiological adaptations of endotherms to maintain body temperature include changes to rate , hibernation or , evaporative cooling and heat exchange . 3 exchange transpiration balance dehydration Xylem cooling The main form of water loss from plants is , which is required to move water up the and for evaporative . Water is also lost when stomata are open for gas . Plants that live in areas of low water availability must achieve a between how much water the plant can afford to lose for cooling , transpiration , exchange of gases and the risk of . 4 exposure concentration stomata woody arid storing Xerophytes internal are plants that live in conditions and have adaptations that equip them to achieve this balance and survive in their hostile environment . They do this by : reducing the of transpiring plant structures to sunlight , reducing the temperature , regulating the opening and closing of the , reducing difference in water between the plant and the outside air , water and producing fruits .
