Clues
- Change in the ecosystems which offsets or neutralizes changes and returns the systems to its origional state or equilibrium (8, 8)
- change in the state of a system causes even greater changes so that it moves further and further from the origional equilibrium (8, 8)
- change the form of energy or matter (15)
- closed, non-living systems no change over time disturbances creates a new different equilibrium (6, 11)
- exchange energy and matter with their surroundings (ie human body) (6, 4, 6)
- Exchange energy but not matter with their surroundings (water cycle- energy from sun is imported but water stays on earth) (6, 6, 6)
- exchange neither energy nor matter with their surroundings (rare in nature usially only founf in controlled lab experiments) (6, 8, 6)
- FLOW- is movement through or within a system energy flows THROUGH the system matter CYCLES continuously WITHIN the system (6, 2, 6, 5)

- Wheat>bug>frog>snake (11, 4, 5)
