The controlled variable is... 14 Closed System 15 Model Representation of the actual system What a system is designed for...it's job/role Systems effect other systems. Objects and energy will leave one system and enter another system. When energy moves from one system (object) to another system (object) Autotroph population Prey population To help us understand systems better by allowing us to study it, perform experiments, etc on a smaller version of the system 3D smaller items, computer simulations, diagrams, pictures. 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 For tracking energy and matter flows so that we can better understand the concept When matter can enter and leave a system. Predator population The system or object under study. Not a representation When matter or energy moves inside of a system
