Answer 2

Answer:

A 1.) The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots.
