6. Abiotic factors? I’m not sure on this one
7. Biosphere
Answer:
<em>The correct option is A) mesosphere only</em>
Explanation:
The solar radiation is not absorbed by the mesosphere of the Earth. Hence, the temperature of the mesosphere decreases as the altitude increases. At the mesopause, the temperature begins to increase with altitude, and this trend continues in the thermosphere.
On the other hand, in the stratosphere, temperature increases with altitude. Hence, other options are not correct.
