It is perfectly believable that there are spores as high as the stratosphere, but that is an inactive form of life, and probably not what you had in mind. I really do not see that the material resources exist to support an active ecosystem in the stratosphere.
no
There could be no life if matter could not change state. Water vapor could not exist, so there would be no rain,
no
So that I could exist.
This is the ozone layer, which is spread out through parts of the stratosphere. It protects the surface from ultraviolet radiation, though some still passes through. Without it, life would not be able to exist as it does now.
We know of no form of life that could exist on Saturn based on our current knowledge of life, Saturn, and the realities of the solar system.No
The ozone in stratosphere affects the life on earth. It protects and shields the surface of earth.
Carbon is essential to life. Life could not exist without it
The stratosphere does, though there is also ozone near the surface. Stratospheric ozone is natural and helpful, keeping most ultraviolet rays out of the atmosphere. Without it, life on earth would not exist as we know it.
12km and above is the stratosphere . Human life cannot exist with that air pressure.The airplanes stay just to the peak of the troposhere.
Expect the unexpected
yes
