Study Notes
Open Systems
- Open systems exchange both matter and energy with their surroundings.
- Example: Ecosystem, where organisms interact with the environment and each other.
Closed Systems
- Closed systems exchange energy but do not exchange matter.
- Although closed systems don’t naturally occur on Earth, they can be modeled.
- Example: "Biosphere II" experiment aimed to replicate a closed system.
- Global cycles of matter, like water and nitrogen cycles, approximate closed systems by maintaining energy flow while limiting matter exchange.
Isolated Systems
- Isolated systems do not exchange either matter or energy.
- No naturally occurring isolated systems exist, except possibly the entire cosmos.
