An open system allows for the exchange of matter and energy between the system and outside of the system. A closed system only allows the exchange of energy; not matter.
The light bulb is a closed system: no mass transfer.
Closed System
An open system in physics is one that can exchange both energy and matter with its surroundings. This is in contrast to closed systems, which can only exchange energy, and isolated systems, which cannot exchange either energy or matter with their surroundings.

A food chain is typically considered an open loop system because it involves the flow of energy and nutrients from producers to consumers and decomposers, without a closed cycle. In an open system, energy and matter are exchanged with the environment, allowing for continuous input and output. In contrast, a closed loop system would recycle all components without external inputs. Therefore, a food chain represents an open loop system.
