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:
2. synthesize its own food 
Explanation:
Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis). 
Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food. 
 
        
                    
             
        
        
        
The type of ecological succession being described in the illustration is primary succession.
<h3>What is primary succession?</h3>
It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.
It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.
A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.
