Explain how bats use ultrasound to catch a prey.

(N/A) Bats use a process called echolocation to navigate and hunt in the dark.
$1$. Bats emit high-frequency ultrasonic waves (sounds with frequencies higher than $20,000 \ Hz$) from their mouths.
$2$. These ultrasonic waves travel through the air and strike the prey (such as an insect).
$3$. The waves are reflected back by the prey as an echo.
$4$. The bat detects these reflected waves (echoes) with its sensitive ears.
$5$. By analyzing the time taken for the echo to return and the nature of the reflected sound,the bat can determine the distance,size,shape,and direction of the prey,allowing it to catch the insect accurately.
