Explanation:
A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher  level of nitrogen and nutrients in it. 
Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in  the water bodies and low oxygen content, the algae grows in slower rate. Besides, slower growth of algae may also affected by the acid rain that happens near Moose lake, which is harmful for algae growth due ti the presence of sulphur.

I would say that the given statement is false. Overexertion in extremely hot temperatures does not help the body to cool itself. <span>Overexertion in hot weather or working in hot, poorly ventilated or confined areas can increase your risk of heat stress. Hope this answers the question. </span>
        
                    
             
        
        
        
The burden of diseases A and B in country Z is that disease B has a higher prevalence than
disease A. That is option D.
<h3>Health statistics of Country Z</h3>
Health statistics is used by professionals to summarize the health status or information on the health of individuals in a particular geographical location.
The basic statistic tools that can be used to check the health status of a population are,
The prevalence rate is the total number of cases of a disease existing in a population divided by the total population.
The prevalence rate of disease A = 225 per 100,000 population while the prevalence rate of disease B = 500 per 100,000 population.
Therefore, the burden of diseases A and B in country Z is that Disease B has a higher prevalence than
disease A.

Answer:
Are you referring to symbiotic relationships between organism? If so, the answer would be parasitism.
One organism, a parasite, takes advantage of another organism at the expense of the host organism. 
Ex. A tick bites a dog for blood to use as food. The dog gets an uncomfortable bug bite and the dog might catch a tick borne disease.
