There are several names, depending on what properties you want to stress.
The Thermosphere ranges from about 80km to 500km. Here the 'temperature' goes up to 1500°C - but the molecules have such rare collisions, that speaking of a gas is somehow wrong. This name is used if you speak about the thermal structure of the atmosphere.
That region might also be called ionosphere (>50km). By that name you stress, that molecules are ionized by radiation.
Also this layer is called heterosphere(>100km) (above the turbopause). Here you stress that no turbulence occurs any more and therefore the atosphere doesn't mix.
regarding your category 'animal life' - there is no such life up there.

The "stratosphere". The lowest level of the atmosphere is the "troposphere", where most weather happens.

Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
