All cycles are closed e.g. Krebs cycle , Kelvin cycle .
Closed System
No its not. A cycle is closed trail
In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.

It is a closed system because water is not made or destroyed there on a large scale.
The phosphorus cycle is considered a closed system because phosphorus does not have a gaseous phase and tends to remain in the solid or dissolved form in ecosystems. This means that phosphorus is continuously recycled within ecosystems through processes like weathering, uptake by plants, and decomposition.
Earth is a closed system in terms of matter, meaning that no new matter is added from outside the system. Matter can cycle within the Earth's systems (such as the water cycle or carbon cycle), but it does not enter or leave the planet.

A cycle is a closed path such that the end vertex of the final edge is the start vertex of the first edge.

The cycle of earning and spending is an example of a cash flow cycle. This mainly focuses on the income and expenditure.
