Answer 1

Answer:

bat produces ultrasonic sound

Answer 2

Answer:

b)Ultra-sonics

Explanation:

Bats send out sound waves using their mouth or nose. When the sound hits an object an echo comes back. The bat can identify an object by the sound of the echo. They can even tell the size, shape and texture of a tiny insect from its echo. Most bats use echolocation to navigate in the dark and find food.

The sound waves produced by the bats are ultrasonic waves. Bats emit sounds at typically 2 or 3 times higher pitch than we can hear. Sounds above human hearing are usually called ultrasonic.
