Answer:
Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? The AMOUNT of oxygen and carbon atoms released by photosynthesis are EXACTLY EQUAL to the atoms of these material contained in carbon-dioxide converted.
Explanation:
 
        
             
        
        
        
6CO2+12H2O+light->C6H12O6+6O2+6H2O
 
        
        
        
The given statement is true.  
The majority of the chronic diseases are not accredited to a single cause, some of the poor lifestyle choices like overuse of alcohol, smoking, lack of physical activity, poor diet, and insufficient relief of chronic stress are the major contributors in the advancement and development of preventable chronic ailments, like type 2 diabetes, obesity, cardiovascular disease, hypertension, and many kinds of cancer.  
 
        
                    
             
        
        
        
The correct answer is - nitrogen and phosphorus.
The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae  will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.
