Question

Ultrasonic sound is used by
(A) Cat
(B) Dog
(C) Bat
(D) Bird

Answer 1

Hint: The audible range of the sound for human is in the range of 20-2000Hz . The sound which is less than the audible sound limit is called infrasonic sound and the sound limit which is greater than the audible sound is called ultrasonic sound.

Complete answer:
The ultrasonic sounds are the high-pitched sounds. The bats use the principle of echolocation to find its prey. The echolocation is the ability of the organisms to find the distance of the object from it by sensing the echoes from the object. These sounds are used by the bats for the purpose of finding its prey.

The bats make the ultrasonic sounds with the high frequency and send the signal to its surroundings. This ultrasonic wave moves in all directions and returns back when it touches the insects, the prey of the bats. The bats again receive back its ultrasonic waves and find at what distance the insects are present and move in that direction. Hence the ultrasonic waves are used by the bats for the finding of its food. Like bats, dolphins and the other whales also find its prey by echolocation in the water.

Hence the correct answer is option(C)

Note: The animals and the birds that can hear the ultrasonic sounds are dogs, dolphins and the bats. The animals that use the infrasonic sounds for its communication are rhinos, octopus, hippos, squid, cod, elephants, whales, pigeons, cuttlefish and the fowl.
