Question

State whether the following statements are true or false.
The smaller an animal, the higher would be its respiratory rate.

• A. True
• B. False

Answer 1

The correct option is A True

Smaller animals have a larger surface area to volume ratios, so they have a higher metabolic rate to compensate for the larger amount of heat loss. The higher metabolic rate of small animals needs a greater delivery of oxygen to tissues around the body and so they have a higher respiratory rate. So, the correct option is 'True'.
