No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it.

Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **
