The correct answer is sacrum; greater trochanter of the femur.

The piriformis is a muscle in the gluteal region of the lower limb. The muscle originates from the front part of the sacrum, which is the triangular bone at the base of the spine found in the gluteal region.

The muscle inserts on the greater trochanter of the femur, which is a powerful protuberance of the femur and a very important part of the skeletal system. The femur is the thigh bone, considered the longest and strongest bone in the human body.

The piriformis originates on the sacrum and inserts on the greater trochanter of the femur. The piliformis is a muscle in the gluteal region of the lower limb. It is one of the six muscles in the lateral rotator group. It is a small muscle located deep in the buttock. It starts at the lower spine and connects to the upper surface of each femur. It functions to assist in rotating the hip and turning the leg and foot outward.

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.
