A closed system maintains itself on a limited amount of resources that are entrenched in that particular system. Energy can be exchanged with other systems, but not any actual matter. Therefore, some of what goes on in the environment is considered a closed system, but not a whole lot. Open systems are much more common. In an open system, necessary resources are renewed and exchanged on a regular basis. Many ecosystems, for example, rely on the sun to constantly import energy into their basic cycles. Then there's a limited amount of nutrients to go around -- such as carbon, nitrogen and phosphorous -- and they're constantly cycled around. Some common cycles include the hydrological cycle, rock cycle and the carbon cycle.

Without additional context, it is difficult to determine. Closed ecosystems are self-sustaining, with minimal exchange of matter with the external environment. Open ecosystems have exchange with the external environment.
Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
No, mollusks typically have an open circulatory system, where the blood flows around the body cavity and directly bathes the organs. This is in contrast to closed circulatory systems found in some other animals where the blood flows through vessels.
Ludwig Bertalanffy describes two types of systems: open systems and closed systems. The open systems are systems that allow interactions between its internal elements and the environment. An open system is defined as a "system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components."[1] For example, living organism. Closed systems, on the other hand, are considered to be isolated from their environment. For instance, thermodynamics applies to closed systems. The idea of open systems was further developed in systems theory. For instance, open systems in systems theory encourage a non-representational and non-referential posthumanist approach that actualize complexity of reality in a non-deterministic framework.
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
