The biosphere is considered an open system because it interacts with its surroundings through the exchange of energy and matter. It receives input of energy from the sun and cycles materials such as carbon, nitrogen, and water with other Earth systems.
In a closed system, matter does not change. In an open system there is a free flow of matter in and out so you can exchange particles, lose particles or gain particles from the outside of the system
A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)
The part of a refrigerator that determines whether it is an open or closed system is the refrigeration cycle, particularly the refrigerant flow. In a closed system, the refrigerant is contained within a closed loop of coils, absorbing heat from the interior and releasing it outside without any mass exchange with the environment. In contrast, an open system would involve the exchange of mass, where refrigerant could enter or leave the system. Most traditional refrigerators operate as closed systems.
Closed. Except for the rare case of humans launching objects into space and meteorites striking the planet (which represent an incredibly miniscule fraction of the total carbon), the amount of carbon in the system remains at a constant mass.
The light bulb is a closed system: no mass transfer.

You might have heard about the open or closed loop system. If it is a closed loop system, then it is referring to the continuous piping loops that are set underground. These loops are to be filled with an anti-freeze-like liquid which is the key to transforming the floor temperature into the geothermal heat pump.
