Develop a PDE-based model that describes the dynamics of a predator-prey ecosystem with the following assumptions:

• The prey population grows following the logistic growth model.

• The predator population tends to decay naturally without prey.

• Predation (i.e., encounter of prey and predator populations) increases the predator population while it decreases the prey population.

• The predator population tends to move toward areas with high prey density.

• The prey population tends to move away from areas with high predator density.

• Both populations diffuse over space.
