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