Answer 1

The most appropriate option for Debbie to use in identifying the type of fish she caught would be a dichotomous key for fresh-water fish using qualitative traits. This is because she is fishing at a lake, which suggests that the fish she caught would most likely be fresh-water fish. Quantitative traits such as eye color, skin color, and texture may vary within a species and are not reliable indicators for identifying the type of fish.
