main idea. A. Sit-and-wait lizards use brief spurts of energy to forage, while the movements of active lizards are more sustained. B. Lizards that are active foragers are able to detect insects even when those insects are stationary, but sit-and-wait lizards are able to detect only moving insects. C. Sit-and-wait lizards tend to have predators that are active, while active lizards tend to have sit-and-wait predators. D. Sit-and-wait lizards have less need for bodies that match their environment than active lizards do because of the ease with which they can break off their tails to escape from predators. E. The body forms and metabolic functions of the two types of lizards differ in ways that support the requirements of their different foraging behaviors. F. Sit-and-wait lizards derive energy for movement from anaerobic metabolism alone, while active lizards rely almost equally on aerobic and anaerobic metabolisms.
