Transcribed Image Text:The yellow perch is a fish found in freshwater lakes. It is a generalist predator,
consuming a variety of prey species, including crayfish, small fish, insect larvae and
snails. You examine the predation rate of yellow perch on snails, and obtain the
following data. Identify the type of functional response, and a plausible reason for
why it has that type of response.
