AP BIOLOGY

Detailed explanation-1: -Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can navigate, hunt, identify friends and enemies, and avoid obstacles.

Detailed explanation-2: -Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments.

Detailed explanation-3: -(1) Bats produce high-frequency sounds to hunt for their prey. (2) Dolphins and other toothed whales use sound waves to locate their prey and navigate their surroundings. (3) Nocturnal oilbirds use echolocation to navigate their surrounding, especially those with poor lighting conditions.

Detailed explanation-4: -Bats navigate and find insect prey using echolocation. They produce sound waves at frequencies above human hearing, called ultrasound. The sound waves emitted by bats bounce off objects in their environment.

Detailed explanation-5: -Fruit bats are the only bats that can’t (and never could) use echolocation.
