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