Among these choices, the most energetically efficient locomotion per unit mass is likely ________.

Question

Quizplus · Accepted Answer

Swimming, especially for large aquatic animals like a 100-kilogram tuna, is generally more energetically efficient per unit mass compared to other forms of locomotion such as running or flying. This is due to the buoyancy provided by water, which reduces the energy cost of supporting body weight, and the streamlined bodies of fish like tuna that allow them to move through water with minimal resistance.
