Process:  - The bat sends out sound waves from their mouth or nose - The sound waves hit an object - Echoes are produced - The echo returns to the bat&#x27;s ears - The bat hears the echo - The bat can figure out where the object is located.  Perturbation hypothesis: suppose More echo waves will bounce happens, how will it affect WEAKER echolocation.  Does the supposed perturbation have an effect (direct or indirect) on the process?

yes
