When matter or energy moves inside of a system The system or object under study. Not a representation When energy moves from one system (object) to another system (object) 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. Predator population 3D smaller items, computer simulations, diagrams, pictures. Prey population
