Write a hypothesis about the effect of dry conditions on earthworm behavior. Use the "if . . . then . . . because . . .” format, and be sure to answer the lesson question, "How is earthworm behavior affected by external stimuli?”

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
