<span>Light
from the sun provides energy for life’s processes. It enables the primary
producers (photosynthetic organisms) such as phytoplankton
and plants to produce organic molecules from abiotic factors. This energy is passed up as primary and secondary
consumers consume these producers and this cycle
continues up the foods chain/web. </span>
 
        
             
        
        
        
Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for reaction of potassium superoxide  with carbon dioxide to produce oxygen and potassium carbonate will be:
