Walking or running are more energetically expensive forms of locomotion than either swimming or flying.
Answer the following statement true (T) or false (F)
True
In contrast to swimming and flying, locomotion on land is, on average, the most energetically costly means of locomotion. Whereas gravity is not an important factor for locomotion in swimming animals, terrestrial animals must overcome gravity each time they take a step. Of even greater importance to walking and running animals, though, is the requirement to accelerate and decelerate the limbs with every step.
