Dolphins rely on echolocation to navigate, communicate with other dolphins, avoid predators, and find mates and food. Echolocation is the use of emitting sounds to determine how far away an object is, how big it is, and what shape it is.

The table shows the reactions of dolphins to noise stimuli from ships and other marine vessels.



Behavior Before Noise Stimuli Behavior After Noise Stimuli
Feeds on fish in territory Feeds on fish outside of territory
Whistles at lower frequencies and high complexity Whistles at higher frequencies and low complexity
Quick response to predators Slow response to predators




Based on the information, what conclusion can be made?


Noise stimuli do not affect dolphins' sensory input or behaviors.


Noise stimuli affect dolphins' sensory input and change their behaviors.


Noise stimuli affect dolphins' sensory input, but there is no change in their behaviors.


Noise stimuli do not affect dolphins' sensory input, but there is a change in their behaviors.

Noise stimuli affect dolphins' sensory input and change their behaviors.

Reason: After noise, dolphins change whistle frequencies/complexity, shift feeding locations, and have slower predator responses, indicating noise disrupts echolocation/sensory input and alters behavior.
