Question
Chapter 42.5, Problem 2CC
Summary Introduction
To explain: How gas exchange requirements of an earthworm are responsible for their coming out on the earth’s surface after heavy rains.
Concept introduction:
The process of gaseous exchange between the circulatory system and the environment is called respiration or respiratory exchange. For earthworms as well as some amphibians, the skin serves as the respiratory organ.

After a heavy rain, earthworms come to the surface. How would you explain this behavior in terms of an earthworm’s requirements for gas exchange?
How do flatworms accomplish gas exchange (obtain oxygen and get rid of carbon dioxide)? What physical feature of flatworms enables them to survive using this method of gas exchange?
Using Daphnia and grasshoppers as specific examples, compare how aquatic arthropods accomplish gas exchange with how terrestrial arthropods accomplish gas exchange?
