Bats. They are blind and rely on their ears to see. They make a slight chatter noise that they use as sonar waves. When the sound waves bounce back to the bat's ears, it allows them to tell where they are or where things are.
animals can have holes for ears or can use smell if they don't have ears
Animals use their ears to hear sounds in their environment, communicate with each other, and detect potential dangers. Ears also help animals maintain balance and orient themselves. Some animals, like bats, use their ears for echolocation to navigate and find prey.
Same way we do.
moles
Some bats use their ears to have sonar vison which lets them move in the dark without using their eyes.
Elephants use energy transfer, manly african elephants, with their ears etc.

Animals have different shaped ears depending on how far in the distance they need to hear. Bats have larger ears because they need to hear from further distances and use sonar. Other animals have smaller ears because they don't need to hear as far.
No, that's what you use to clean their ears when they do have ear mites.
Not all animals that hear have external ears like many mammals do, but many can sense the vibrations that we perceive as sound through other sensory organs, which you might call "ears".
Themselves. They watch and listen for prey with eyes and ears, chase the prey, then kill it.
Snakes do not have ears because they had not needed to use them over the hundred of thousands of years hunting, and successful reproduction. Snakes though because of not having hearing their other senses have heightened.
