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