It is much easier a small animal to run uphill than a large animal- becauseIt is easier to carry a small body weight-Smaller animals have higher metabolic rate-Small animals have a lower O-2 requirement-The efficiency of muscles in large animals is than in the small animals-

Question

Toppr Admin · Accepted Answer

Small animals use more metabolic energy per unit mass than large animals to run on a level surface- If the cost to lift one gram of mass one vertical meter is constant- small animals require proportionally smaller increases in metabolic cost to run uphill-xA0-

It is much easier for a small animal to run uphill than for a large animal, because
It is easier to carry a small body weight.
Smaller animals have higher metabolic rate.
Small animals have a lower $O_{2}$ requirement.
The efficiency of muscles in large animals is less than in the small animals.
