What is binomial nomenclature please help​

Binomial nomenclature is a binomial system of naming a species. A binomial name is comprised of two parts, i.e. the generic name (genus name) and the specific name (or specific epithet, in botanical nomenclature). It is often in a Latinized form.

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.
