Type II Functional Response- Hollings Disk Equation.docxDescription
Student Introduction: In the type II functional response, the rate of prey consumption by a predator rises as prey density increases, but eventually levels off at a plateau (or asymptote) at which the rate of consumption remains constant regardless of increases in prey density (see also TYPE I and TYPE III FUNCTIONAL RESPONSE). Holling's disk equation, named after experiments he performed in which a blindfolded assistant picked up sandpaper disks from a table, describes the type II functional response.
