Question

USING PYTHON Thank you.

Overview For this lab, we will write an eco-system simulation for two species: predator and prey. The prey is the primary food source for the predator. During each round of the simulation, the number of prey will increase or decrease (due to predation, other deaths, and births), and the number of predators will increase or decrease (due to births and deaths) Instructions Write a function (simulate) that simulates the counts of two species: one predator and one prey. The arguments of this function are Sample Value Argument initialPred initialPrey preyGrowth predationRate predShrink Description The initial number of predators The initial number of The rate at which births of prev exceeds natural deaths The rate of predation The rate at which deaths of predators exceeds births without food 50 0.25 0.01 0.05 predFedBirthRateThe rate of increase in predators in the presence of food Your function will collect the counts of each species in two lists: predatorCounts and preyCounts. The function will have a loop, representing rounds of the simulation, which repeats until one of the values (predator or prey) is zero. At each iteration, you will update the count, and append these counts to the predatorcounts and preyCounts lists, of predators and prey according to the following formulae: preyprey,x (1+ preyGrowth- predationRate x predators, predators, predators, x1- predShrink+ predFedBirthRate x prey Note 1: preyiti is merely a Mathematical notation to show the relationship with how the values change from one round to the next. You cannot use this notation in Python. Note 2: preyiti is the number of prey on the current timestep, and prey, is the number of prey on the previous timestep. You should have a variable called prey'
