Matching Pairs Systems and Models (part 3) - Review for Ecology UnitOnline version assignment by Benjamin D Morgan 1 How does the number of predators affect the prey population? The independent variable is... 2 Energy Transfers 3 System Importance 4 Model Importance 5 Closed System 6 Open System 7 Types of models 8 Model 9 Flows within 10 System Interaction 11 System Function 12 Actual System 13 Energy Transformations 14 How does the number of predators affect the prey population? The controlled variable is... 15 How does the number of predators affect the prey population? The dependent variable is... The system or object under study. Not a representation For tracking energy and matter flows so that we can better understand the concept Systems effect other systems. Objects and energy will leave one system and enter another system. When matter can enter and leave a system. What a system is designed for...it's job/role Autotroph population Representation of the actual system To help us understand systems better by allowing us to study it, perform experiments, etc on a smaller version of the system When energy moves from one system (object) to another system (object) When matter cannot enter or leave a system, but energy can enter/leave Energy can change from one type of energy to another type of energy when it interacts with a system 3D smaller items, computer simulations, diagrams, pictures. When matter or energy moves inside of a system Prey population Predator population
