In this paper, the local derivative in time is replaced with the Caputo-Fabrizio fractional derivative of order $\alpha\in(0, 1)$. A two-step fractional version of the Adams-Bashforth method is formulated for the approximation of this derivative. To enhance the correct choice of parameters when numerically simulating the full-system, we examine the stability analysis of the main equation. Two important examples are drawn to explore the dynamic richness of the predator-prey model with Holling type. Simulation results at different instances of $\alpha$ is in agreement with the theoretical findings.
