<span>Carbon is the only element that can form many different compounds. Each carbon atom can form four chemical bonds to other atoms. This allows it to form rings and chains.</span>
        
             
        
        
        
Then the submerged aquatic plants will note be able to receive light for photosynthesis. then those submerged aquatic plants will not have food/nutrients to survive, hence die. aquatic animals will not receive sufficient oxygen from those submerged aquatic plants, hence die also. 
decomposes will breakdown all dead organisms to release carbon dioxide, and also deplete oxygen concentration during decomposition process. 
eventually, habitat is rendered not livable. only the algae continue to proliferate uncontrollably at the water body surface.
        
             
        
        
        
<h2>Answer:</h2>
Mesosphere
<h2>Explanation:</h2>
The atmospheric layer that protects the Earth against danger of the rocks is the mesosphere. This layer is above the stratosphere. The temperature drops in this layer to about -100 degrees Celsius. This is the coldest region of the atmosphere. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. It becomes cold enough to freeze water vapor in its atmosphere into ice clouds.
