Question

answer this please and please try to be quick there is a timer

Answer 1

Explanation:

Some animals use echos sound waves reflected off objects in their path to navigate and find food at night or in dark locations such as caves. This is known as echolocation.

bats

Bats emit pulses of high-pitched sounds beyond the range of human hearing and then listen for the echoes that are produced when these sound waves bounce off objects around them. The folds in a bats ear are uniquely suited to detect these echoes which give them information on the location, shape and size of surrounding objects, including really small objects such as mosquitos. Bats can also use echoes to tell the direction an object is moving.

whales and dolphins

Marine mammals such as whales and dolphins also use echolocation to locate things at long distances, beyond the range of vision, and also in the depths of the ocean where it is very dark. Whales use echolocation for navigation and to locate food. Dolphins also emit clicks with their nasal tissue and use the echoes to find their way around and to hunt. They also use echolocation to communicate with other members of their group and to avoid predators.

oilbirds and swiftlets

Oilbirds emit clicks and use the echoes to hep them navigate in total darkness. Swiftlets use echolocation for navigation in the dark and also for social purposes. The ears of these birds, unlike those of bats, don't show any modifications that make them particularly suited to echolocation.

shews

Shrews are known to emit ultrasonic sound and use the echoes to locate insects and other prey. They open and close their mouths rapidly to emit quick pulses of low intensity sound as they get closer to their prey. Shrews also use echolocation for navigation. They find their way through leaf litter or in the darkness of tunnels under snow with the help of echoes produced by sounds they emit.

hope this will help
