It's both closed and open systems.
Early earth was an open system due to the meteors that brought heat, which was energy, and they were also matter.
Mainly with respect to energy.
The crux of system thinking is interaction. System thinking is a language for describing and understanding the forces and interrelationships that shape the behavior of systems.
Coral don't have circulatory systems. They just have a gastrovascular system!
open: matter and energy can pass freely in and out closed: only energy can pass freely isolated: nothing can pass freely
An isolated system does not exchange energy or matter with its surrounding.
A closed system or an open system. An open can also exchange matter. An Isolated system can exchange neither.
It's both closed and open systems.
With respect to matter, Earth is a closed system and with respect to energy, Earth is an open system.
In an open system,both energy and matter flow.In an closed system only energy flow.In an isolated system neither energy nor matter flow.
A closed system does not let any matter enter or exit, and no energy enters or exits the system.
Early Earth was an open system because energy and matter such as light energy and meteors were bombarding the Earth.
Systems can be classified as open, closed, or isolated. Open systems exchange both matter and energy with their surroundings, closed systems only exchange energy, and isolated systems exchange neither. These classifications are based on the extent of interaction between the system and its environment.
An open system is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept (see below). An open system should be contrasted with the concept of an isolated system which exchanges neither energy, matter, or information with its environment.a closed system is isolated from environmental influences. In reality completely closed systems are rare.
The bird will be best represented as an open system if you include the respiration of the bird and the feathers it drops occasionally. If you neglect those factors you could represent it as a closed system. It will NOT be an isolated system since it does work on its surroundings and its surroundings do work on it - along with some amount of heat transfer from the bird to its surroundings.
