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