Which step is part of the formation of a batholith? heat and pressure change a pluton into metamorphic rock. a single pluton enlarges into a huge mass by melting the rock around it. lava flows across a mountain or plain, and then hardens into rock. many plutons clump together as they rise through the crust.

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.
