Question

It is much easier for a small animal to run uphill than for a large animal, because:

• A. It is easier to carry a small body weight.
• B. Smaller animals have a higher metabolic rate.
• C. Small animals have a lower O2 requirement.
• D. The efficiency of muscles in large animals is less than in the small animals.

Answer 1

The correct option is B Smaller animals have a higher metabolic rate.

It is much easier for a small animal to run uphill than for a large animal, because smaller animals have higher metabolic rate. Metabolism results in release of energy. Hence, smaller animals have more energy and that makes it more easier for them to run uphill than a large animal.
