The following are sample test questions. 1. Consider a predatory-prey interaction between two species. (i) Create a casual loop diagram describing the system's dynamics. (ii) Create a simple discrete-time mathematical model of the predator-prey interaction as- suming unlimited resources in the ecosystem. Clearly state the system's state variables and the assumptions made, and describe the parameters used. 2. Consider the following discrete-time model equation: In ( + 2
