A type I functional response, occurs when a predator’s rate of prey consumption increases linearly with an increase in prey density until the predator is satiated.

The type II functional response, occurs when the number of prey consumed slows as prey population density increases. 

In a type III functional response, prey consumption is low when prey population density is low, consumption is rapid when prey population density is moderate, and prey consumption slows when prey population density is high.
