Bats are sensitive to very small changes in frequency of the reflected waves. What information does this allow them to determine about their prey?

A. Size 

B. Speed 

C. Distance 

D. Species 

As discussed in the chapter, many species of bats find flying insects by emitting pulses of ultrasound and listening for the reflections. This technique is called echolocation. Bats possess several adaptations that allow them to echolocate very effectively.
