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