Without these three things, it wouldn't really be an ecosystem in the first place. Without producers, no food would be made, without consumers, there would be nothing to eat what is produced, and without decomposers, nothing would be broken down. Each part is connected to each other, and all of them are crucial to the survival of an ecosystem.

These are the main components of an ecosystem. Plants are the primary producers, and without them, most life on this planet cannot survive.
Even if you use the example of the virus, they need a producer, some organism that produces blood cells, or other useable source to reproduce.

No because an ecosystem is made of producers, consumers and decomposers. Without them, there is NO ecosystem!

An ecosystem, a contraction of "ecological" and "system", refers to the collection of components and processes that comprise, and govern the behavior of, some defined subset of the biosphere. The term is generally understood to refer to all biotic and abiotic components, and their interactions with each other, in some defined area, with no conceptual restrictions on how large or small that area can be. To many, ecosystems, like any other system, are governed by the rules of systems science and cybernetics, as applied specifically to collections of organisms and relevant abiotic components. To others, ecosystems are primarily governed by stochastic events, the reactions they provoke on non-living materials and the corresponding responses by organisms.
So by definition, an ecosystem could have only abiotic components. A sandy beach ecosystem with no life in it.

Oh no, everything is in a cycle. Nothing would exist if just one thing was off. Say a plant died out. The herbivores that rely on it will die, then those who eat it would die out too, and so on with other carnivores after they have eaten all the other animals. Everything is interrelated and interdependent, nothing can live on its own.

Without copying Wikipedia, I would say no-ish.
A closed ecosytem needs energy to cycle.
A very open system could exist without them, but it would be unstable.
