What do you already know about athlete’s foot? What other information is related to the question?
· Athlete’s foot is caused by Tinea pedis, which is a fungus.
· Tinea pedis is a dermatophyte, which means it feeds on skin.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· Atavism involves a return to a primitive form, which is not what occurs with athlete’s foot.
· Since commensalism involves a relationship in which one species benefits while the other species is unaffected, it can be disregarded as an answer.
· Mutualism is a relationship in which both species benefit. This is not what occurs in the case of athlete’s foot.
· Since the fungus is feeding on the skin of the host and the host is receiving no benefit, athlete’s foot is an example of parasitism.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use symbiotic relationships in a new situation. If you got an incorrect answer, did you remember that commensalism benefits one species while the other is unaffected, or that mutualism benefits both species? Did you have trouble extending the concept of symbiotic relationships to determine the correct answer?

Of the following four islands at the same latitude, which one likely possesses the fewest species?
A. 1,000 square kilometers in area and 300 km from the mainland B. 3,000 square kilometers in area and 100 km from the mainland C. 100 square kilometers in area and 3,000 km from the mainland D. 300 square kilometers in area and 1,000 km from the mainland E. All islands are at the same latitude, so they are all likely to have the same species richness.
