Less

Explanation:

 The thermosphere has less air pressure as compared to the mesosphere as the thermosphere layer are above the mesosphere surface and the standard pressure of the air is 100 kilo pascal.

The air pressure is so negligible at the highest point of thermosphere in which the air particles can easily travel long distance before hitting the another molecule of the air.

The UV radiations and the X rays are absorbed by the thermosphere so that is why the temperature increases and there is decrease in the air pressure.

the first plants to make the transition

explanation:

answer they showed that organic molecules such as amino acids could be produced from inoragnic molecules;
