How does a bat use sound energy to catch its prey?

Back

A bat uses echolocation, emitting sound waves that bounce off objects, allowing it to determine the location and distance of its prey.

Can light sources be both natural and man-made?

Back

Yes, light sources can be natural (like the sun) or man-made (like light bulbs).
