What a system is designed for...it's job/role Representation of the actual system For tracking energy and matter flows so that we can better understand the concept When energy moves from one system (object) to another system (object) 3D smaller items, computer simulations, diagrams, pictures. When matter cannot enter or leave a system, but energy can enter/leave When matter or energy moves inside of a system Autotroph population Systems effect other systems. Objects and energy will leave one system and enter another system. The system or object under study. Not a representation Predator 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
