Liver contains a enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the production of oxygen gas (O2) and liquid water (H2O).
Hope I helped
        
             
        
        
        
In photosynthesis, using light energy, plants convert CO2 and H2O into O2 and C6H12O6
CO2= carbon dioxide 
H2O= water 
O2= oxygen 
C6H12O6= glucose
        
                    
             
        
        
        
<span>I believe it is light, but this is kind of a confusing question. Technically there is a independent and dependent variable in the question. The variable being manipulated is light, and the earthwork activity depends on the light. </span>
