Snakes Can Often Be Found Resting on Asphalt Highways at Dusk;

question 6

Multiple Choice

Snakes can often be found resting on asphalt highways at dusk; what biological factor motivates them to engage in this behavior?

• A) Ectothermy-a snake's body temperature will match the environment; rocks and asphalt cool more slowly than the surrounding ground.
• B) Predation-as higher-level consumers, snakes need to hunt continuously and are more successful on the smooth surface of a roadbed at night.
• C) Camouflage-the background color of asphalt makes detection by owls and other nocturnal predators difficult.
• D) Mating-locating compatible mates can be difficult among the grasses, brush, and shrubs of typical snake habitat.
