C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.
