Question

Which of the following is most likely to have a much higher breathing rate?

विकल्प

• man

• fish

• dog

• sparrow

Answer 1

fish

Explanation:

The rate of breathing in aquatic animals is much faster than in terrestrial animals. This is because the amount of dissolved oxygen in water is relatively low compared to the amount of oxygen in the air, so aquatic animals require a faster breathing rate to obtain enough oxygen.
