The correct answer is: stratosphere.
This is because their temperatures are rising instead of decreasing.
There are 4 primary layers of the atmosphere on Earth:
Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.
Stratosphere (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.
Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer
Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
Answer:Amphibians evolved during the middle of the Devonian period (416 to 359 million years ago) from the lobe-finned fish of the vertebrate class Sarcopterygii. Species within the genus Ichthyostega (members of the Labyrinthodontia subclass) are considered by some scientists to be the earliest amphibians.
Explanation:
Answer:
<em>Yes, the abiotic components interact with the biotic components in an ecosystem.</em>
Explanation:
The abiotic components are the non- living components of an ecosystem. The biotic components are the living components of an ecosystem. Abiotic factors such as sunlight, temperature etc directly affect the biotic components.
For example, the light of the sun is an abiotic component which provides energy to the biotic components, plants, to produce food. Soil is also an abiotic component which provides nutrients and water for the plants which are biotic components.
