2
Q
isolated system
A

no
interactions with anything outside the system boundary
3
Q
closed system
A

finite number of resources are continually recycled
4
Q
open system
A
inputs and outputs of energy and matter
5
Q
feedback
A
when equilibrium is upset by a sudden input/output change that forces stores to be altered
6
Q
dynamic equilibrium
A
changing balance of inputs and outputs
7
Q
positive feedback
A
big permanent change
knock on consequences
increases output and instability
8
Q
negative feedback
A
small temporary change
quickly fixed
promotes stability and dynamic equilibrium
