Question

For which of the following reason it is much easier for a small animal to run uphill than for a large animal?

Options

• It is easier to carry a small body weight.

• The efficiency of muscles in large animals is less than in the small animals.

• Small animals have a lower O₂ requirement.

• Smaller animals have a higher metabolic rate.

Answer 1

Smaller animals have a higher metabolic rate.

Explanation:

The body size has an inverse relationship with the basal metabolic rate. Smaller animals have a greater metabolic rate, which means they have more energy and can sprint uphill more easily.
