Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place. 
Fungi are very important groups of organisms. They are natural "recyclers". 
In a food chain or web they can be classified as decomposers. 
Decomposers are organisms that takes feeds on dead and decaying organic matter. 
The produce useful materials and releases nutrients from life back into nature. 
Killing them off by applying fungicides is a damaging act to their sustenance. 
Without decomposers such as fungi, the ecosystem becomes less stable  and soil nutrients will not be properly recycled. 
 
        
                    
             
        
        
        
<span>Enzymes are catalysts in chemical reactions. What this means is that they speed up chemical reactions, which in turn means that all the actions necessary for our metabolisms occur as a result of catalysts. This goes from fighting illnesses and diseases to dissolving food. We couldn't live without them because our metabolisms would be so slow that we would die as nothing could work.</span>
