How do bats use echolocation to find food?

Bats use echolocation to locate food and navigate in the dark. They emit high-frequency sound waves from their mouths or nostrils, which bounce off objects in their environment. By listening to the returning echoes, bats can detect the size, shape, distance, and location of objects, such as flying insects. This ability is crucial for hunting in complete darkness, especially for insect-eating species, allowing them to find and capture prey with great precision.
