Echolocation

Echolocation is a technique used by animals like bats, dolphins, and whales to navigate and hunt by emitting sounds and interpreting the returning echoes to determine the position and distance of objects. Bats can fly and hunt in complete darkness using high-frequency sounds, while marine animals like dolphins and some whales use echolocation to orient themselves in their environment.

What is the primary method animals use to determine the position of objects around them?

• Infrared detection

• Magnetic fields

• Echolocation

• Visual cues

How does the time taken for sound to return help animals?

• It helps them identify the type of object

• It indicates the distance of the object

• It shows the speed of the object

• It reveals the color of the object
