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