Question

State whether the following statement is true or false:

Fish and earthworm exchange gases during respiration in the same way.

Answer 1

This statement is false.

Explanation:

While both animals rely on diffusion to exchange gases, they use entirely different respiratory structures and environments:

• Fish use specialized organs called gills to extract dissolved oxygen from water. Water enters the mouth and passes over the gill filaments, where gas exchange occurs.
• Earthworms lack specialized respiratory organs and exchange gases directly through their thin, moist skin from the air or soil.
